Results of Research on SARS-CoV-2 Targeted Detection Kit

 

Research on SARS-CoV-2 Targeted Detection Kit

The new crown is a common problem and challenge faced by scientists around the world, but in order to overcome it, our scientists have conducted a lot of research on it. As the understanding of COVID-19 has become deeper and deeper, scientists have also developed and produced various Kind of COVID-19 testing products. At present, researchers are turning to the area of ​​concern that SARS-CoV-2 related enzymes contribute to the pathogenicity and spread of COVID-19. Antibody inhibitors derived from these enzymes may play a role in helping to develop treatments.

 

EpiGentek further classifies and organizes the kits for these research directions. At the same time, some new products are gradually attracting people's attention as a way to better understand how to fight viruses. There are currently three main ways:

 

1. SARS-CoV-2 proprotein convertase (PC) activity and inhibition analysis kit

The SARS-CoV-2 spike glycoprotein has a furin/PC cleavage site on the boundary of the S1/S2 subunits, which can be cleaved by furin secreted by host cells and bacteria and/or furin-like PCs. 

Unlike SARS-CoV, SARS-CoV-2 entering cells is pre-activated by furin and/or furin-like pc, reducing its dependence on target cell protease entry. 

It has been proven that the lysis and activation of S protein is essential for the SARS-CoV-2 spike-mediated virus-ACE2 binding, cell-cell fusion, and virus entry into human lung cells.

SARS-CoV-2 preprotein convertase (PC) activity and inhibition analysis kit

Significance: Furin and/or PC-based SARS-CoV-2 S1/S2 lysis increases the entry and replication of SARS-CoV-2 into cells and eventually develops higher COVID-19 pathogenicity. Therefore, the detection of SARS-CoV-2 targeting Furin/PC lytic activity will help determine why the sensitivity and pathogenicity of COVID-19 are different in different individuals. 

The screening of inhibitors will help develop effective COVID-19 treatment drugs by blocking the SARS-CoV-2 lysis at the S1/S2 boundary.

 

EpiGentek provides two new kits to observe the inhibitory effect of pro-proteolysis activation from different angles.

2. SARS-CoV-2 total IgG/IgM and neutralizing antibody measurement kit

SARS-CoV-2 infection usually induces an antibody response. The antibody can bind to SARS-CoV-2 spikes, and only a small part has a neutralizing function. Only neutralizing antibodies can block the effect of SARS-CoV-2 spikes and inhibit the SARS-CoV-2 virus from infecting new cells.

 

SARS-CoV-2 total IgG/IgM and neutralizing antibody measurement kit

Significance: Measuring the total SARS-CoV-2 specific IgG/IgM helps determine whether an individual is infected with SARS-Cov-2. 

However, it is more important to detect SARS-CoV-2 neutralizing antibodies in a quantitative and high-throughput format:

 

1.) It can help determine whether symptomatic infected individuals have acquired protective immunity from COVID-19 and how long the neutralizing antibody persists after infection

 

2.) It helps to accurately evaluate therapeutic antibodies against SARS-CoV-

 

3.) This will greatly benefit the development of effective vaccines.

EpiGentek provides two different types of kits for the quantitative measurement of SARS-CoV-2 antibodies in human samples. 

The first is the SeroFlash SARS-CoV-2 IgG / IgM ELISA rapid kit, which can quickly measure SARS-CoV-2 IgG and IgM antibodies from plasma or serum sample input. 

The other is the SeroFlash SARS-CoV-2 neutralizing antibody rapid determination kit, which can quickly quantify the amount of specific SARS-CoV-2 neutralizing antibodies from samples including serum, plasma and various body fluids.

3. SARS-CoV-2 Spike-ACE2 binding activity and inhibition analysis kit

The process of SARS-CoV-2 entering human host cells occurs through the binding of the surface unit S1 of its spike protein to the cell receptor angiotensin converting enzyme 2 (ACE2). 

ACE2 is ubiquitous and is widely expressed at different levels in the lungs, heart, kidneys, blood vessels, brain, intestines and testes. 

ACE2 also mainly binds to cell membranes and is usually less present in the circulation. It has been found that the increased expression of ACE2 in the nasal epithelium and lungs is related to the higher rate of SARS-CoV-2 infection and the severity of COVID-19, respectively. 

A new observation suggests that increased circulating ACE2 concentrations may be related to increased incidence and mortality of COVID-19. 

In addition, SARS-CoV-2 invasion will degrade ACE2 on the cell membrane and may increase the concentration of soluble ACE2 in the circulation.

 

SARS-CoV-2 Spike-ACE2 binding activity and inhibition analysis kit

Significance: SARS-CoV-2-ACE2 binding activity determination will truly reflect the level of functional ACE2 in binding to SARS-CoV-2. 

This assay can not only detect ACE2 binding activity under healthy and diseased conditions, but also measure changes in ACE2 levels under various experimental interventions, including in vivo ACE2 epigenetic regulation, in vivo and in vitro ACE2 activity inhibition (such as: antibodies and Small molecule inhibitors) and environmental impact (e.g.: smoking).

 

It is also due to the complex interaction of SARS-CoV-2-ACE2 under normal (healthy) and abnormal (previous diseases and viral infections), as well as the current COVID-19 pandemic and its possible recovery. 

Inhibitor screening is necessary to help develop effective drugs, vaccines and therapeutic antibodies that target COVID-19.

 

EpiGentek provides two new kits: CoviDrop SARS-CoV-2 Spike-ACE2 Binding Inhibitor Rapid Screening Kit, which can help quickly screen out Spike-ACE2 binding immunological or chemical inhibitors. And CoviDrop SARS-CoV-2 Spike-ACE2 binding activity/inhibition assay kit, used to measure Spike-ACE2 binding activity and inhibition of biological samples. 

Each assay kit provides a fast, easy-to-follow procedure that can be used for manual or high-throughput analysis.
