With the now global outbreak of COVID-19, SARS-CoV-2 early diagnostics and infection prevention and control has become critical. Elabscience® can also provide the following antibodies for SARS-CoV-2 (2019-nCoV, COVID-19 virus) research:

Proteinase K
Proteinase K is a kind of high activity proteinase of subtilisin, which is used to degrade proteins in biological samples. It can be used to digest various proteins, and it can be used in a variety of molecular biology, cell biology and other related experiments, such as genomic DNA extraction, enzyme digestion and removal, cell permeability and so on.
Proteinase K is mainly used for the production of nucleic acid extraction kit, especially for nucleic acid extraction from samples of nucleic acid diagnosis and detection in vitro diagnosis (IVD) industry.

Shortage of supply
Due to the outbreak of “2019-nCOV”, the demand for nucleic acid detection is soaring, and the supply of raw materials for detection reagents is also very tight, including Proteinase K extracted from nucleic acid.

A large wave of Proteinase K is coming!
In order to alleviate the supply pressure of Proteinase K and provide sufficient raw material support for the detection of new coronavirus, our R&D team with strong strength of Elabscience® has solved the problems of batch production time, product quality and yield in a short time by using the international leading protein purification platform.

Valid Period2~8°C for two years. RT for one year.
Purity≥95% by SDS-PAGE
ApplicationGenomic DNA Purification Kit, RNA Purification Kit, Gene Diagnostic Kit, IHC, ISH and other possible application.
Activity≥30 U/mg
Capacity15~20 kg/Month

Product characteristics

  • Recombinant expression in yeast
  • Activity ≥30 U/mg
  • DNase and RNase free
  • Recommend usage 50~200 μg/mL

Activity result
Elabscience® standard production process requires that the activity ratio ≥30 U/mg. In fact, the activity ratio exceeded the expected production standard, content the application requirements of customers.
Unit definition: One unit is defined as the amount of enzyme that catalyzes the formation of 1 μmol of tyrosine per minute at pH 7.5 at 37°C.

Calibration curve
According to the absorbance A275 for the vertical axis, the different concentrations of tyrosine as the horizontal axis, the standard curve was drawn.

Detection of DNase and RNase residues
Use DNase and RNase detection kit to detect the DNase and RNase residues with different Lots of Proteinase K. The results showed that there were no DNase nor RNase in Proteinase K.

SARS-CoV/CoV-2 (2019-nCoV) Antibodies

Since the SARS-CoV-2-Spike protein and Nucleocapsid Protein (NP) are the biomarkers of 2019-nCoV, and angiotensin convertenzyme 2 (ACE-2) is the main surface receptor to SARS-CoV-2 , it is important to fully understand the role these proteins play in SARS-CoV-2 infection. Elabsicnece® offers a variety of antibodies to investigate the mechanisms of the SARS-CoV-2 life cycle.

SARS-CoV/CoV-2 (2019-nCoV) Proteins

Spike Protein

The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor, and S2 contains basic elements needed for the membrane fusion.

Nucleocapsid Protein (N protein)

The coronavirus N protein is abundantly produced within infected cells. N protein has multiple functions, including binding to viral RNA to form the ribonucleocapsid and has also been proposed to have roles in virus replication, transcription and translation.In host cells, N proteins have been shown to cause deregulation of the cell-cycle, inhibit the production of interferon, up-regulate the production of COX2, up-regulate the activity of AP1, and induce apoptosis in serum deprived cells-of all which may have possible pathological consequences.

Membrane and Unstructural Proteins

Membrane protein and Envelope protein are the key to the efficient assembly of coronavirus.
3C-like proteinase of SARS-CoV-2 virus is a key protein in RNA replication.
Papain-like protease (NSP3) plays an important role in the precursor cleavage of various viral proteins to form a series of functional proteins needed in viral replication.
3C-like proteinase and Papain-like protease are important targets for the development of antiviral drugs, which can inhibit virus replication and reduce related mortality.

ACE2 Protein

ACE2 (Angiotensin Converting Enzyme 2) is the receptor of SARS-CoV-2 infected cells, and the infection process depends on the serine protease TMPRSS2. Blocking the interaction between S protein and ACE2 is an effective way to treat coronavirus infection.

Proteinase K

Proteinase K is a kind of high activity proteinase of subtilisin, which is used to degrade proteins in biological samples. It can be used to digest various proteins, and it can be used in a variety of molecular biology, cell biology and other related experiments, such as genomic DNA extraction, enzyme digestion and removal, cell permeability and so on.
Proteinase K is mainly used for the production of nucleic acid extraction kit, especially for nucleic acid extraction from samples of nucleic acid diagnosis and detection in vitro diagnosis (IVD) industry.

SARS-COV-2 Peptide

In view of the hot targets, the Elabscience® expert team has designed and synthesized the SARS-COV-2 (2019-nCoV) related peptide, providing comprehensive support.
