SARS-CoV-2 Neutralizing Antibody Rapid Test Cassette (Colloidal Gold Method)

The SARS-CoV-2 Neutralizing Antibody Rapid Test Cassette (Colloidal Gold Immunochromatographic Assay) is intended for the qualitative detection of SARS-CoV-2 neutralizing antibodies in human serum, plasma, or whole blood specimen. This kit is intended for use to identify individuals with an adaptive immune response to vaccination or natural infection.

Neutralization antibody is a soluble protein secreted by adaptive immune response cells. It specifically binds to the receptor-binding domain (RBD) of the virus, thus blocking the binding of the RBD to angiotensin-converting enzyme 2 (ACE2) on the surface of human cells. Through the above process, neutralizing antibodies can prevent genetic materials of the virus from entering the cell for proliferation, thus preventing the virus from infecting a cell and neutralizing virus toxicity.

This kit applied the chromatographic immunoassay technology is a blocking detection tool. Using purified receptor-binding domain (RBD), protein from the viral spike (S) protein, and the host cell receptor ACE2, this kit is designed to mimic the virus-host interaction by direct protein-protein interaction on the test strip.
