Technology

KRISHGEN BIOSYSTEMS uses its proprietary enzymatic assay and immunoassay technologies to develop cost effective and user friendly research and diagnostic tools that better equip scientists to effectively do their research. KRISHGEN’s focus is to utilize three platform technologies to develop highly sensitive and stable assays for use on open immunoassay platforms.

The technologies include KRISHZYME™ enzyme/enzyme cycling technology for assays in the range of µmole/L sensitivity; GENLISA™ technology for assays in the range of pg/ml sensitivity; and KRISHGEN’s KRIBIOLISA™ technology for assays in complex matrices and difficult protein detections.

The ultimate goal is to provide researchers tool for detection and measurement of proteins which are robust, sensitive and reproducible.

INSULIN ANALOGS& GLP-1 AGONIST ASSAYS

What are Insulin Analog medicines?
An insulin analog is an altered form of insulin, different from any occurring innature, but still available to the human body for performing the same action ashuman insulin in terms of glycemic control.
Through genetic engineering of the underlying DNA, the amino acid sequence ofinsulin can be changed to alter its ADME (absorption, distribution, metabolism,and excretion) characteristics.
Officially, the U.S. Food and Drug Administration (FDA) refers to these as”insulin receptor ligands”, although they are more commonly referred to asinsulin analogs.
In July 2021, the U.S. FDA approved the first interchangeable biosimilar insulinproduct, indicated to improve glycemic control in adults and paediatric patientswith Type 1 diabetes mellitus and in adults with Type 2 diabetes mellitus.Semglee (insulin glargine-yfgn) is both biosimilar to, and interchangeable with(can be substituted for), its reference product Lantus (insulin glargine), a long-acting insulin analog. Other countries are sure to follow.

What are GLP-1 receptor agonist medicines?
GLP-1 receptor agonist medi- cines, also called incretin mimet- ics, are a typeof incretin-based medicine for type 2 diabetes. This type of medicine is basedon the action of hormones called in- cretins, which help control how thepancreas works. One type of incretin, called GLP-1, causes your pancreas toproduce more insulin after you eat and helps keep blood glucose levels in thenormal range.
These medicines (exanatide, lixisenatide, liraglutide and semaglutide) copy, or mimic, the action of GLP-1 made by your body. The effects of GLP-1only last for a few minutes, but GLP-1 receptor agonists medicines can last forhours or days.

Gene Therapy has emerged as a promising future to disease treatment and personalized therapies. It is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

 

In vivo gene therapy involves direct delivery of a therapeutic gene into the target cell in a patient’s body. This can be carried out by both viral and non-viral vectors, though the most popular emergence in vectors has been the Adeno-Associated Virus vector (AAV). AAV binds to a cellular receptor, enters the cell, migrates to the nucleus, and delivers a single-stranded DNA genome to establish a latent state for long-term gene expression in the absence of co-infection with a helper virus.

 

Genome editing is now also widely used for making gene knockout/knock-in animals and plants as well as genome-modified cell lines. Cas9 protein is a purified nuclease from E coli using Cas9 gene of Streptococcus pyogenes; it is a ready-to-use product containing a nuclear localization signal (NLS) for genome editing experiments resulting site-specific cleavage of double stranded DNA.

Krishgen has a range of AAV ELISA kits and anti-AAV ELISA titration kits for a rapid and reliable way of quantifying AAV vectors or antibodies against AAV, based on a monoclonal antibody sandwich technique. We also manufacture genome-editing protein: wtCas9, eSpCas9(1.1), AsCpf1 that exhibit higher efficiency, specificity and undetectable off -target effects in vivo and in vitro.

Krishgen provides a wide catalog of relevant tools for COVID-19 research and clinical diagnostics, including ELISA, RT-PCR, RAPID kits and various proteins.

The ongoing pneumonia outbreak in the city of Wuhan is caused by the highly infectious coronavirus 2019-nCoV, named by the World Health Organization on January 12nd, 2020. This new virus belongs to the Betacoronavirus Genus, which also includes SARS CoV (2003) and MERS CoV (2012). The sequence similarity between 2019-nCoV and MERS-CoV is 40%, while that between 2019-nCoV and SARS-CoV is 70%.

Krishgen has been at the forefront of the SARS-CoV-2 response, manufacturing various specific assays and tests from April 2020. These products have supported a variety of research, as well as vaccine and therapy development.

Primarily, Krishgen is working on accurate, specific ELISA for antigen, and antibody studies related to COVID-19. Whether you are working with Spike protein (RBD, S1 and S2) or N-protein, and with IgG or IgM, Krishgen has the right immunoassay for you. Our species-specific ELISA kits allow for antigen and antibody quantification in human as well as animal models.

 

Krishgen is currently the only company in the world commercially manufacturing several of these ELISA. If you require support in choosing the right product, get in touch with our technical support team today!

 

To provide a complete testing solution for your research, Krishgen also manufactures a wide range of human and animal biomarkers and cytokines.
