Elabscience Company Introduction Video

Are there any cautions for the label?

 The label should contain free primary amines or N-terminal, and the sample should not contain Tris, glycerin, and reagents with amino.

Could this biotin labeling kit be used for labeling other proteins in addition to antibodies?

 The principle of biotin labeling kit is the formation of stable amide bond between activated Biotin and amino of label. In addition, N-terminal of protein can be labeled. Protein contains primary amines, such as lysine, can be labeled.

When labeling protein with this kit, does the reaction ratio is the same proportion of 20:1 as labeling antibodies?

 The molecular weight and lysine amount of protein should be considered. In general, it is recommended to label according to the concentration of 2 mg/mL. If the amount of lysine is about 10~15, the reaction ration can be 1:20. The proportion will be increased if the amount of lysine is more.

Can this kit be used for small or trace labeling?

 The assay procedure in the manual is used for labeling 0.1~2 mg antibody. If you need to mark a smaller amount, we have a special trace labeling method used to label 20-100 μg antibody and the reaction system is 100 μL. (So the amount of Biotin should be increased if the labeling concentration is less than 2 mg/mL.)

How to detect the labeling efficiency?

 The labeling kits on sale have their optimized labeling method. The labeling efficiency of these kits are generally above 90% from our test. In addition, antibodies in our ELISA kits are also labeled with Biotin labeling kit. The biotin labeling efficiency can be determined by detecting the biotin amount with our Biotin Detection Kit.

Can the Filtration tube in this kit be repeatedly used?

 The Filtration tube in this kit can be repeatedly used no more than 3 times, but must be washed after the assay finished use the following method: Add purified water and gently pipetting for several times. Then add 0.2M NaOH, incubate for 10 minutes and centrifuge. Wash the tubes with purified water. The tube can put in the water for short term storage, while it should be preserved in 20% ethanol for long term storage. The used tubes should avoid of dry and keep moist.

How long is the shelf life of the activated biotin after dissolution?

 The unopened freeze-dried biotin powder can be stored stably for 1 year at 4 ℃, and it can be stored for 4 weeks in the dark if sealed properly after opening/dissolving..

How to judge whether some specific substance (e.g., folic acid) can be labeled with FITC or not?

The target substance can be labeled if it contains free amine, and the amount of primary amine (lysine) should be considered for proteins. Small molecules can be determined according to the amino number. The containing nitrogen heterocyclic ring of folic acid contains 1 amine, so it can be labeled with FITC theoretically. But the amine on this site has a weak nucleophilicity, the labeling effect may not good and it should be judged according to the purpose of their experiment by customers.

Is the protein with a molecular weight of 3.8 kD suitable to be operated with a 3 kD Filtration tube?

 No. If your target protein has a molecular weight of 3.8 kD, you have to choose the Filtration tube with a blocked diameter of less than 3.8/3, otherwise there is possibility of skip or plugging aperture.

If my target protein has 43 lysine, but I just want to label less than 5 biotin molecules. Is it necessary to take quality control labeling? Are there any methods to verify the labeling effect and amount?

 Considering the spatial configuration, the reaction ratio optimized by Elabscience is 1:20, so that 1 antibody will be labeled with 3~6 Biotin molecules. If you want to control the labeling amount to be less than 5, you should control the molar ration and take pre-experiment, and estimate the labeling amount with Our Biotin Detetcion Kit.

What concentration of primary antibody should I use?

For antibodies which the suggested working dilutions are listed as “Assay Dependent” this simply means that the optimal dilution should be obtained by the end user. However, we are always available to provide assistance.

Can I receive a free sample of a product?

 Generally, we do not offer free or trial sized samples for testing purposes. Our policy is that if an antibody does not work as specified on the datasheet, we will offer a replacement or refund (Except the promotion period. Detailed promotion information will be displayed on our website, or you can contact our sales). If the antibody is being used in an untested species or application, we cannot offer a replacement or refund.

How can I determine whether an antibody may detect in an untested species?

– Elabscience are unable to guarantee that an antibody will work in an untested species, even if the sequence alignment is high. There are many variables involved in the determining whether an antibody will bind in another species.

– If there are no alternatives available, and it is necessary for you to consider purchasing an antibody for use in a species that is not tested, we recommend checking the sequence alignment of the immunogen with the protein you are interested in.

Is the information on the datasheet up-to-date and correct?

 The datasheets contain the most up-to-date information we have available to us about this product. Where we find additional information, the datasheets are updated live on the website immediately,and you can contact our service team for any questions about Elabscience datasheet.

How should I choose a positive control?

 If you require a suitable positive control, please contact our technical support team and we would be happy to help. Additionally, make sure that the cell line or tissue being used is from one of the species listed on the data sheet.

What antigen retrieval method should I use with this antibody?

 We do not always have information available on the most suitable antigen retrieval method for an antibody in immunohistochemistry. This will often require a certain amount of optimization by the end user. Visit our IHC protocols page for more information on antigen retrieval methods.

Instrumentation sample preparation and storage for ELISA assays

How to deal with tissue or cells?

Normally, the amount and ratio of each reagent a fully automated microplate ELISA analyzer needs are not the same as in our kit, so it’s not applicable. Whereas if you can tell Cell lysates: For adherent cells, gently wash the cells with moderate amount of pre-cooled PBS and dissociate the cells by trypsin. Collect the cell suspension into the centrifugal tube and centrifuge for 5 minutes at 1000×g. Discard the medium and wash the cells for 3 times with pre-cooled PBS. For each 1×106 cells, add 150-250uL of pre-cooled PBS (0.01M, pH=7.4) to keep the cells resuspended. Repeat the freeze-thaw process for several times until the cells are lysed fully. Centrifuge for 10minutes at 1500×g at 2 – 8℃. Remove the cell fragments, collect the supernatant to carry out the assay. Avoid repeated freeze-thaw cycle.
Cell culture supernatant: Collect samples and centrifuge for 20 minutes at 1000×g at 2 – 8℃. Collect the supernatant to carry out the assay.
Tissue homogenates: Generally, mince the tissues to small pieces and rinse them in ice-cold PBS (0.01M, pH=7.4) to remove excess blood thoroughly. Tissue pieces should be weighed and then homogenized in PBS (tissue weight (g): PBS volume (mL) =1:9) with a glass homogenizer on ice. To further break the cells, you can sonicate the suspension with an ultrasonic cell disrupter or subject it to freeze-thaw cycles. The homogenates are then centrifuged for 5 minutes at 5000×g at 2 – 8℃, collect the supernatant to carry out the assay.Plasma: Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 15 minutes at 1000×g at 2 – 8℃ within 30 minutes of collection. Collect the supernatant to carry out the assay. Hemolysis samples are not suitable for ELISA assay.

How to collect serum and plasma?

Reading at dual wavelengths is to correct the optical density contributed by the plate wells and other nonspecific interference. Our plates are chosen for their optical quality, Serum: Allow samples to clot for 2 hours at room temperature or overnight at 4℃ before centrifugation for 15 minutes at 1000×g at 2 – 8℃. Collect the supernatant to carry out the assay. Blood collection tubes should be disposable, non-endotoxin.
Plasma: Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 15 minutes at 1000×g at 2 – 8℃ within 30 minutes of collection. Collect the supernatant to carry out the assay. Hemolysis samples are not suitable for ELISA assay.

Saliva, Urine, milk, tear and other types of biological fluids

In general, use a sterile container to collect fluids, then centrifuge it at 1000-5000×g at 2 – 8℃ for 5-20min to remove particulates, collect the supernatant to carry out the assay.


Samples should be assayed within 7 days when stored at 2-8℃, otherwise samples must be divided up and stored at -20℃ (≤1 month) or -80℃ (≤3 months). Avoid repeated freeze-thaw cycles. Centrifuge again before assaying to remove any additional precipitates that may appear after storage.

How to perform an ELISA assay as perfectly as possible?

How to calculate/ deal with the raw datas?

After correct the average OD values, plot a four parameter logistic curve on log-log graph paper, with standard concentration on the x-axis and OD values on the y-axis, many softwares could also help to deal with it, such as Origin( recommended), CurveExpert.

Target analyte in tested samples

 It’s recommended to test fresh samples by ELISA, which could avoid false positive or negative results caused by the degradation or decomposition of target analyte during long time storage.

Dilution factors and diluent

 Dilution ratio: Refer to the specific protocol or published papers, or consult to our technical support.

Recommended diluent: Standard & Sample Diluent provided in the ELISA kit, we could provide more vials of it for free for specific application, just tell us when you place the order.

Assay procedure

Following the protocol strictly, here are some hints
a. Establish the complete Standard Curve for each assay.
b. Ensure the precise volume for each reagent addition
c. Try to finish the liquid addition for each reagent as soon as possible, better not over 10 min.
d. Keep constant speed for liquid addition to each well
e. To get more accurate experiment result, it’s recommended to conduct the ELISA assay as soon as possible once you receive the kit.


PolyPeptide dissolution

Dissolving a polypeptide is a very complex process, and it is generally difficult to determine a suitable solvent quickly. Usually take a little for a preliminary test, and do not dissolve completely before determining the proper solvent.

The following methods can help you choose the right solvent:

 Determine the charge specificity of the polypeptide, set the acidic amino acid Asp (D), Glu (E) and C-terminal COOH to -1; basic amino acid Lys (K), Arg (R), His (H) and N-terminus NH2 is +1 and the charge of the other amino acids is zero. Calculate the net charge number.

 If the net charge number is >0, the polypeptide is alkaline and dissolved in water; if the peptide does not dissolve, add 10% acetic acid dropwise with vortexing. The peptide solution can also be warmed slightly. Longer peptides (over 20 amino acids) with a small overall net charge might require the addition of a stronger acid. Trifluoroacetic acid (TFA 10-50 µL) is often used to solubilize peptides but it is not cell-friendly and thus is used only when acetic acid fails to help solubilize the peptide. After the addition of TFA, the peptide should be diluted to approximately 1 mL with deionized water.

 If the net charge number is <0, the peptide is acidic and dissolved in water; If the peptide does not dissolve, add ammonium hydroxide (NH4OH 10-50 µL), and dilute the peptide to approximately 1 mL with deionized water.

Note: Caution must be used, however, with peptides that contain cysteine (C), as the used of alkaline pH can cause disulfide bond formation.

 If the net charge number = 0, the polypeptide is neutral and generally needs to be dissolved with an organic solvent such as acetonitrile, methanol or isopropanol, DMSO and the like. It has also been suggested that urea is required to dissolve highly hydrophobic polypeptides.

PolyPeptide preservation

Generally long-term preservation of polypeptides need to avoid light, and should be stored below -20 ℃, short-term can be stored at 4℃. It can be transported at room temperature for short periods of time. Polypeptides are very stable at -20℃, especially when they are lyophilized and stored in a desiccator. Before they are exposed to air, lyophilized polypeptides can be naturally heated up at room temperature, which reduces the effect of humidity. When lyophilizing is not possible, the best way is to store it in small amount of working samples.

For polypeptides containing Cys, Met or Trp, deoxidation buffers are essential for their dissolution, as the polypeptides are prone to air oxidation, and nitrogen or argon protection can reduce oxidation before sealing. Polypeptides containing Gln or Asn are more susceptible to degradation and have a shorter shelf life than normal peptides that do not contain these problematic amino acid.

Lower readings in samples and standards

Please be sure to verify the expiration date and store the kits properly, at the meantime you can check whether the parameter page is the top reading or not.


How to dilute the sample?

Sample dilution factor provided in the manual can be referred. If not, you can select three dilution multiples of high, medium and low for pre-experimental determination according to the results in the literature.

Why is the fluorescence value of standard significantly different from those provided in the manual?

Different instruments use different methods, so there is no comparability between the fluorescence value measured by different instruments, but this won’t affect the measurement results.

The importance of antibody reproducibility

In recent years, researchers have found that there has been a serious “repeated crisis” in antibody related research.

According to the statistics of Nature, 80% of researchers can’t repeat other researcher’s experimental results, and 60% can’t repeat their own experimental results.

The quality problem of antibody is one of the main culprits leading to the unrepeatable experiment. The human protein atlas project has tested 9,000 antibody products from 29 suppliers, and more than 50% of them fail to work effectively.

It is estimated that US $350 million and US $800 million are wasted annually on the use of unidentified antibodies in the United States and around the world, such antibodies can lead to experimental failure or unreliable results.

The quality of antibody is one of the main reasons leading to unrepeatable experiments.

At present, the American Society of Pathologists and Laboratory Quality Center released a guideline on the analysis and verification principles of IHC testing (Principles of Analytic Validation of Immunohistochemical Assays), at the CAP2014 annual meeting in the United States. It was recently published in the Arch Pathol Lab Med., the article clearly pointed out the necessity of routine IHC testing for cytology samples.

In scientific research, different scientific researchers have slight differences in operating methods, reagent configuration, and experimental details. In addition, the poor repeatability of antibodies can easily cause different degrees of incompatibility and cause uncontrollable experimental results. In order to minimize this uncontrollability, Elabscience® combined with Lifespan’s immunohistochemical quality inspection platform to perform a secondary immunohistochemical quality inspection on the antibodies produced by Elabscience®. To screen high-quality immunohistochemistry antibodies according to Lifespan’s quality inspection standards, and provide more professional inspections for your immunohistochemistry experiments. In addition, Elabscience® provides you with a complete set of immunohistochemistry solutions, one-stop related reagents to solve your problems.

Antibody validated by IHC

Immunohistochemistry (IHC) is a highly useful technique for detection and quantification of target epitopes (e.g. proteins, structures, cellular components) in a wide variety tissue types. Applicable to fresh, frozen and FFPE samples, IHC staining utilizes high specificity antibodies for visualization of target expression patterns, providing quantitative, qualitative and spatiotemporal information on processes taking place in tissues. Antibody-epitope interactions are visualized through secondary staining of samples with an additional antibody that has been conjugated to either a color-producing enzyme (chromogenic staining) or a fluorophore (immunofluorescent staining, or IF).

In the future, we will display more validated antibodies by IHC, and plan to use different validation methods to improve antibody standards.

Monkeypox Introduction

Source and Characteristic

Monkeypox virus (MPV) is an orthopoxvirus that causes a disease with symptoms similar, but less severe to smallpox. While smallpox was eradicated in 1980, monkeypox continues to occur in countries of central and west Africa. Two distinct clade are identified: the west African clade and the Congo Basin clade, also known as the central African clade. In May 2022, multiple cases of monkeypox were detected in several non-endemic countries, making it urgent to further understand the epidemiology, source of infection and mode of transmission of this disease.

Fig. Monkeypox epidemic map (Source: World Health Organization; May 21)

Monkeypox virus (MPV) is a double-stranded DNA virus belonging to orthopoxviruses of the Poxviridae family. It is one of the human orthopoxviruses, including variola (VACV), vaccinia (CPX) and vaccinia (VACV) viruses. Monkeypox virus is about 200-400 nm in size, brick or oval in shape, with stable DNA structure, which can repair itself when mutation occurs.

Transmission and Pathogenesis

Monkeypox is a zoonosis: a disease that is transmitted from animals to humans. Cases are often found close to tropical rainforests where there are animals that carry the virus. Evidence of monkeypox virus infection has been found in animals including squirrels, Gambian poached rats, dormice, different species of monkeys and others.

Human-to-human transmission is limited, with the longest documented chain of transmission being 6 generations, meaning that the last person to be infected in this chain was 6 links away from the original sick person. It can be transmitted through contact with bodily fluids, lesions on the skin or on internal mucosal surfaces, such as in the mouth or throat, respiratory droplets and contaminated objects.

Monkeypox virus invades human body from respiratory mucosa, multiplies in lymphocytes and invades blood stream to produce transient viremia. After intracellular reproduction, the cells invade the blood stream and run to the whole body skin reproduction, causing lesions.



The incubation period of monkeypox can range from 5 to 21 days. The febrile stage of illness usually lasts 1 to 3 days with symptoms including fever, intense headache, lymphadenopathy (swelling of the lymph nodes), back pain, myalgia (muscle ache), and an intense asthenia (lack of energy). The febrile stage is followed by the skin eruption stage, lasting for 2 to 4 weeks. Lesions evolve from macules (lesions with a flat base) to papules (raised firm painful lesions) to vesicles (filled with clear fluid) to pustules (filled with pus), followed by scabs or crusts.

The disease is self-limiting, with symptoms usually lasting 2 to 4 weeks and going away without treatment, the proportion of patients who die has varied between 0 and 11% in documented cases. The main difference between the symptoms of smallpox and monkeypox is that monkeypox causes lymph nodes to swell, whereas smallpox does not.

Monkeypox Detection Method

1. What is Lateral flow assay?

The lateral flow assay kit is a chromatographic immunoassay for the qualitative detection of Ag/Ab. The test method is based on antigen-antibody. It has two letters which are test (“T”) line and control (“C”) line on the surface of device. Test line and control line in the result window are not visible before applying any samples. This visual evaluation enables qualitative analysis. This rapid detection card is easy to operate and cost-effective.

A Rapid Chromatographic Immunoassay Kit for Monkeypox Virus-Specific IgG and IgM Antibodies in Human Whole Blood, Serum, or Plasma. During the test, the sample is dropped into the sample well of the reagent, and the chromatography is performed under the capillary effect. The human monkeypox antibody (IgG and IgM) in the sample binds to the colloidal gold-labeled monkeypox antigen, diffuses to the test area, and is captured by coated monkeypox monoclonal antibody II (anti-human IgG and anti-human IgM), forming a complex to aggregate in the test area (test line IgG and test line IgM); the quality control area is coated with goat anti-mouse IgG antibody, which captures the colloidal gold-labeled antibody to form a complex and aggregate in the quality control area. The highly specific antigen-antibody reaction and colloidal gold immunochromatography technology are combined to qualitatively detect the content of IgG and IgM antibodies to monkeypox virus in serum, plasma or whole blood. Test principle: the combination of the analyte with the capture antibody on the membrane and the colloidal gold labeled antibody produces a color change, and the color intensity change has a correlation with the concentration of the analyte.


2. What is Reverse Transcription Polymerase Chain Reaction (RT-PCR)?

Reverse transcription-polymerase chain reaction is a molecular technique commonly called RT-PCR. PCR stands for polymerase chain reaction, a laboratory method used to amplify specific regions of DNA for diagnosis and analysis in medical research. Reverse transcriptase PCR, instead of DNA, uses mRNA as the starting template.

Real-time RT-PCR is a modified version of PCR in which the enzyme called reverse transcriptase is used. This enzyme facilitates the conversion of an RNA sequence into its complementary DNA sequence. RT-PCR works on this principle of reverse transcription. It is a real-time technique that combines reverse transcription of RNA into DNA and the amplification of target DNA. It’s a qualitative means of detecting a particular RNA sequence with a high degree of accuracy and sensitivity.

The Monkeypox virus nucleic acid Test Kit is performed on the applicable instrument to detect DNA extracted from lesion exudate specimens. It utilizes the monkeypox virus conserved sequence of F3L gene as multiplex real time PCR amplification target regions.

The fluorescent quantitative PCR instrument can automatically draw a real-time amplification curve based on the detected fluorescent signal, so as to realize the qualitative detection of the monkeypox virus at the nucleic acid level. The multiplex real time PCR detection system includes a pair of primers and probes for internal control (RNase P). The positive control and negative control included in the kit can be used as an external control in every test run. The results of internal and external control can be used to monitor correct specimen collection, handling and real time PCR process.


3. What is Reverse enzyme linked immunosorbent assay (ELISA)?

ELISA is an antigen antibody reaction. It is a plate based assay technique which is used for detecting and quantifying substances such as peptides, proteins, antibodies and hormones. An enzyme conjugated with an antibody reacts with colorless substrate to generate a colored product.

ELISAs are typically performed in 96-well polystyrene plates. The serum is incubated in a well, and each well contains a different serum. A positive control serum and a negative control serum would be included among the 96 samples being tested. Antibodies or antigens present in serum are captured by corresponding antigen or antibody coated on to the solid surface. After some time, the plate is washed to remove serum and unbound antibodies or antigens with a series of wash buffer. To detect the bound antibodies or antigens, a secondary antibodies that are attached to an enzyme such as peroxidase or alkaline phosphatase are added to each well. After an incubation period, the unbound secondary antibodies are washed off. When a suitable substrate is added, the enzyme reacts with it to produce a color. This color produced is measurable as a function or quantity of antigens or antibodies present in the given sample. The intensity of color/ optical density is measured at 450nm. The intensity of the color gives an indication of the amount of antigen or antibody

SARS-CoV-2 is a virus that can cause severe acute respiratory failure and spread on a large scale in the population. Its existence and transmission pose a serious threat to human life and physical health, and it has caused the most serious public health incident in the world in recent years.

SARS-CoV-2 has several structural proteins including spike (S), envelope (E), membrane (M) and nucleocapsid (N). The spike protein (S) contains a receptor-binding domain (RBD), which is responsible for recognizing the cell surface receptor, angiotensin converting enzyme-2 (ACE2). It is found that the RBD of the SARS-CoV-2 S protein strongly interacts with the human ACE2 receptor leading to endocytosis into the host cells of the deep lung and viral replication.

To effectively and quickly screen out SARS-CoV-2 asymptomatic, severely ill patients and recovered patients among large-scale populations, the application of molecular biology and immunology technology is particularly important. In order to help the SARS-CoV-2 research, Elabscience has developed 9 types of SARS-CoV-2 related antigen and antibody ELISA kits, which can meet customer research needs.

Sandwich ELISA

Sandwich ELISA (or sandwich immunoassay) is the most commonly used elisa method. This format requires two antibodies/antigens specific for different epitopes of the antigen/antibodies. These two antibodies/antigens are normally referred to as matched antibody/antigen pairs. One of the antibodies/antigen is coated on the surface of the micro plate and used as the capture antibody/antigen to immobilize the tested analyte. The other antibody/antigen is conjugated with biotin or other markers to facilitate the detection of the analyte.

Sandwich ELISA

Competitive ELISA

Generally, Competitive ELISA (or competitive immunoassay) is applied for small molecular detection. The sample antigen competes with the pre-coated antigen for binding to a specific amount of labeled antibody. This assay only requires a single antibody conjugated to biotin commonly to facilitate the detection of the analyte.

Enzyme-linked immunosorbent assay established a quantitative ELISA method based on the selectivity and specificity of antibody and antigen recognition. The main principle of ELISA: one of these immune components is fixed in the holes of the solid phase (enzyme plate), and the detected target in the sample interacts with the antibody-antigen system. This interaction can be observed by enzymes in enzyme markers and indicate whether antibody-antigen binding occurs. The added substrate is transformed by coupling enzyme, resulting in color change, which can be measured by Microplate Reader.

Advantages of ELISA

Immunolabelling technology is an immunobiochemistry analysis method to identify and determinate the trace and ultra-trace bioactive substances. The principle of immunolabeling is to covalently combine the marker (such as fluorescein, radioactive isotope, enzyme, biotin, etc.) with another compound, and then a multicomponent complex will form due to the specific reaction between the marked compound and tested compound. After the separation of unbound marked compound, you can observe and detect the experiment result with kinds of precise detection instruments.

The immunolabeling technology can be applied to take qualitative, quantitative or semi-quantitative analysis of samples, and it can also be used to study the location in cells or tissues. Elabscience® offers Fluorescence Labeling Kits and Biotin Labeling Kits with high-quality for researchers. Browse all Labeling Kits in below table.

CFPAC-1 STR Authentication

CFPAC-1 STR Authentication

One of the most serious issues facing the biomedical research community today is the authentication of human cell lines used in research and drug development as models of normal and cancer tissue.

Short tandem repeat (STR) is a short tandem repeat structure with a core sequence of 2-6 bases. In the early 1990s, STR locus was first used as an important genetic marker in human paternity testing.

According to the results of STR report, cell growth status (whether there is a cross-contamination with other cells) and the strain of cell lines can be confirmed.

At the present, cell line STR-profiling would appear to represent the greatest value to the scientific community for authenticating human cell lines unambiguously, quickly, and for the least expense.

Apoptosis is a complex and active death, involving the activation, expression and regulation of a series of genes.

When apoptosis occurs, a series of apoptotic processes are programmed, such as phosphatidylserines valgus outside of the cell membrane, mitochondrial membrane ΔΨm changes, caspase activation, DNA fragmentation and so on.

Different methods of apoptosis research

Apoptotic event line

Abnormal apoptotic mechanism can cause cells to lose control, which is closely related to the occurrence and development of many diseases such as tumors. Accurate detection of apoptotic cells is essential in the apoptosis study.

Elabscience® Cell Apoptosis Assay Products

Elabscience® has successfully developed multiple apoptosis detection products based on the most commonly used principles.

DNA Fragmentation

When cells undergo apoptosis, a large number of viscous 3′-OH are produced by breakage of chromosomal DNA. Under the action of deoxyribonucleotide terminal transferase (TdT), the deoxyribonucleotides and derivatives of fluorescein, peroxidase, alkaline phosphatase or biotin can be labeled to the 3′-terminal of DNA, so that apoptotic cells can be detected.

Caspase Activacion

Caspase family plays a very important role in the process of cell apoptosis. Caspase-3 is a key executive molecule, which plays a role in many pathways of apoptotic signal transduction. Caspase exists in the cytoplasm in the form of zymogen and in the early stage of apoptosis, the caspase is activated which eventually leads to apoptosis.

Phosphatidylserine Extemalization

It occurs at early apoptosis and runs through the whole cell apoptosis. Annexin V can bind to valgus phosphatidylserine under the action of Ca2+. Annexin V with DNA dyes such as PI and 7-AAD can distinguish living cells, early apoptotic cells, late apoptotic cells and dead cells.

Decrease of Mitochondrial Transmembrane Potential

The decrease of mitochondrial membrane potential is considered to be the earliest event in process of cell apoptosis. JC-1 dye exhibits different fluorescence emission due to different mitochondrial membrane potential. Cell apoptosis can be detected by detecting the change of cell membrane potential by JC-1 emission light.


Elabscience® Caspase 3 Activity Assay Kit can detect the activity of Caspase 3 in cells or tissue lysis.

Detection principle

Caspase (Cysteine-requiring Aspartate Protease) is a protease family that plays an important role in the process of apoptosis. Caspase 3 (also known as CPP32, Yama, or apopain) is a member of the CED-3 subfamily of Caspases and is one of the critical enzymes of apoptosis. Caspase 3 is the most studied Caspase in mammalian cells. Caspase 3 can be used to cut proCaspase2, 6, 7, 9, and cut specifically many substrates of Caspase directly, including PPAR (poly ADP-ribose), the inhibitor of Caspase-activated deoxyribonuclease (ICAD), gelsolin and fodrin. Protein shearing mediated by Caspase 3 are important parts of the molecular mechanism of apoptosis. In addition, Caspase 3 also plays a key role in the process of nuclear apoptosis including chromatin condensation and DNA fragmentation as well as cell blebbing. Caspase 3 exists in the form of prozyme in the normal state and has no activity. However, during the apoptosis stage, activated Caspase 3 consists by two large subunits and two small subunits, which cleavages the corresponding substrate of endochylema or cytoplasmic nuclear and eventually leads to apoptosis.

This kit is used to conjugate Caspase 3 sequence-specific peptides acetyl-Asp-Glu-Val-Asp p-nitroanilide (Ac-DEVD-pNA) to yellow group p-nitroaniline (pNA). When the substrate is cut by Caspase 3, the yellow group pNA is dissociated. pNA has an absorption peak at 405 nm. Measure the OD value at 405 nm and then

Caspase 3 activity can be calculated accordingly.

  3. It has been reported that the activity of Caspase 3 can’t be detected in few types of apoptosis, which may be due to the existence of a mechanism independent of the activation of Caspase 3, and other signaling pathways in the mechanism of apoptosis need to be considered. In this case, there is no significant change in the activity of Caspase 3 by using this kit.
  4. Lysis Buffer in this kit can be used in other Caspase activity assay kits byElabscience®. And the protein sample can test other Caspase activity.
  5. pNA (4-nitroaniline) is toxic. Please be careful when operating, and pay attention to effective protection to avoid direct contact with human body or inhalation. pNA solidifies at lower temperatures and sticks to the bottom, wall or cap of centrifugal tube. It can be incubated in water bath at 20~25°Cfor a short time until it is completely melted.
  6. When the activity of Caspase 3 in the sample is very low. Confirm whether the phenomenon of apoptosis is obvious or not firstly. If the apoptosis is obvious and we confirm that Caspase can be activated, please adjust the time of apoptosis and find a time point which Caspase 3 activation is stronger. And then repeat the test.
  7. This kit is for research use only.For your safety and health, please wear lab clothes and gloves. Instructions should be followed strictly, changes of operation may result in unreliable results.

SARS-CoV-2 Entry Receptors

The invasion of host cells is the most important part of coronavirus (CoV) infection. The envelope spike (S) glycoprotein is responsible for CoV cell entry and host-to-host transmission. For productive entry into host cells, viruses attach to specific cell surface receptor molecules. This is the case of CoV, whose use of distinct entry receptor molecules is responsible for their broad host range and tissue tropism.

SARS-CoV-2 Cytokine Storm

After the virus invades the body, if the body cannot produce enough specific immune response to effectively remove the virus, it will continue to strengthen the non-specific inflammatory response to eliminate the virus in an inefficient way. This not only cannot effectively remove the virus but will aggravate infection, tissue ischemia and hypoxia and even necrosis, and eventually lead to non-specific inflammatory response out of control to trigger cytokine storms.

The SARS-CoV-2 is causing great damage to human health all over the world. SARS-CoV-2 is a RNA virus, which is more prone to mutation than DNA virus. There are two aspects of SARS-CoV-2 mutants that are thought-provoking: First one is spike protein (s), especially the key receptor binding domain (RBD). Mutation or mutation accumulation may enhance the binding ability of SARS-CoV-2 spike protein to receptor ACE2, and increase the transmission or pathogenicity of the virus. The other one that the mutation may change the key epitope of antigen, reduce the affinity of screened neutralizing antibody, cause immune escape, and reduce the protective effect of vaccine and neutralizing antibody.

Elabscience® has developed nearly 140 SARS-CoV-2 mutant proteins, which can be used to study the potency of antibodies and vaccines.

Study the characteristics

The binding ability of the mutant protein N501Y(U.K. Variant) to ACE2 increased nearly 9 times, while the binding ability of the mutant proteins K417N,E484K and N501Y(South Africa Variant ) to ACE2 increased nearly 3 times.

Detect the neutralizing antibody reaction

The latest research shows that there is antibody escape in SARS-CoV-2 mutants, and the efficacy of antibody drugs approved or being developed against SARS-CoV-2 will be uncertain.

Verify the SARS-CoV-2 antigen detection kit

The antigen detection kit mainly uses N protein as the detection marker. In the process of mutation, the N protein of SARS-CoV-2 also showed some high frequency mutations.

Evaluate the effect of SARS-CoV-2 vaccine

The impact of the SARS-CoV-2 mutant to the vaccines is a widely concerned problem. Some enterprises have begun to lay out the development plan for the mutant vaccine.

Elabscience® Cytokines are small secreted proteins released by immune cells that serve to regulate the immune system, which involve in autocrine, paracrine and endocrine signaling, also regulate the maturation, growth and responsiveness of various cell types. Elabscience® provides a comprehensive catalog of recombinant cytokines with excellent lot-to-lot consistency, superior activity and significantly low endotoxin levels, including Chemokines, Interferons(IFNs), Interleukins, and Tumour Necrosis Factors(TNFs), Cylony Stimulating Factors(CSFs), Growth Factors and Other Cytokine-Related Proteins.

Immune Checkpoint Proteins

Immune checkpoints are regulators of the immune activation. They consist of stimulatory and inhibitory pathways that maintain self-tolerance and assist with immune response. Stimulatory Immune checkpoints augment immunological responses against pathogens. On the contrary, inhibitory Immune checkpoints negatively regulate T-cell activation. In cancer, immune checkpoint mechanisms are often activated to suppress the nascent anti-tumor immune response, and PD-1, PD-L1, CTLA-4, CD28, OX40 are hot targets for cancer immunotherapy.

Chromatography is a most frequently used laboratory technique for separation and purification of biomolecules mixture. The mixture is dissolved in the mobile phase (a kind of fluid), which carries it through the stationary phase (a structure holding another material). The separation is based on differential partitioning between the mobile and stationary phases.

According to the different separation mechanism and principle, chromatography techniques are classified into different types for separation and purification process of the various target biomolecules. There are 4 types of commonly used chromatography techniques: Affinity chromatography, Ion exchange chromatography (IEC), Gel filtration (also known as Size-exclusion chromatography (SEC) and molecular sieve chromatography), and Hydrophobic interaction chromatography (HIC).

As a professional biotechnology company devoted to provide the best reagents and consumables for scientists, Elabscience® is committed to expand our product line and more high-quality products and services for scientific research. We have collected the most popular and acclaimed chromatographic media in one page. View and discover the enjoyable products!

Affinity chromatography

Affinity chromatography is a powerful chromatography technique of separating and purifying proteins based on the highly specific interaction between antigen and antibody, enzyme and substrate, or receptor and ligand. Such interactions including hydrogen bonding, ionic interaction, disulfide bridges, hydrophobic interaction, etc. Affinity chromatography are widely recognized for their high selectivity, high resolution and high capacity.

Ion exchange chromatography

Ion exchange chromatography (IEX) is a practical chromatography process that separates ions and polar molecules based on their respective charged groups. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids.

Gel filtration chromatography

Gel filtration chromatography, also known as size exclusion chromatography (SEC), is a chromatographic method that separates molecules by their size or molecular weight. SEC can be used for wide ranges of separation and purification of components with large molecular weight differences and low resolution requirement, such as proteins, polysaccharides and other macromolecules.

Hydrophobic interaction chromatography

HIC is a useful method for purification and separation of biomolecules based on their surface hydrophobicity. HIC can be applied in the separation and purification of hydrophobic proteins such as aromatic and aliphatic compounds. In HIC, the matrix material is lightly substituted with hydrophobic groups, such as methyl, ethyl, propyl, octyl, or phenyl groups.
