2019-nCoV Neutralizing Antibody Test

A NEWLY LAUNCHED TEST KITS FOR COVID-19 DIAGNOSIS AND VACCINE EVALUATION

This kit is used for the in vitro qualitative derermination of Neutralizing Antibodies comcentration in humanserum/plasma or whole blood samples.

Neutralizing antibody (NAb) is a naturally-produced antibody as part of the immune system's response. These antibodies inhibit or destroy the influence of foreign factors that invade the body. Neutralizing antibodies can be triggered by infection or vaccination, produced by B lymphocytes,
and bind to antigens on the surface of pathogenic microorganisms, thereby preventing the pathogenic microorganisms from adhering to target cell receptors and preventing cell invasion.

SARS-CoV-2 uses the surface spike protein (S protein) to attach and invade host cells. The neutralizing antibody can recognize the virus surface protein, block the virus from binding to specific receptors on the cell surface, and prevent the virus from continuing to invade human cells . Neutralizing antibodies are antibodies that block virus invasion. Antibodies such as IgG/IgM are antibodies produced by the body after virus invasion. Evaluate vaccine efficacy, monitor infection rate, herd immunity and protective immunity, and evaluate vaccine efficacy during clinical trials and after mass vaccination.
