Introduction:
In order to satisfy the critical, global need for serology assays that can complement nucleic acid (PCR) tests for diagnosing COVID-19 infection, Jinjian launched 2019-nCoV IgM/IgG Antibody Test Kit, which is based on the indirect immunochromatography, it is used for qualitative detection of novel coronavirus (SARS-CoV-2) IgM/IgG antibodies in human serum, plasma and venous whole blood specimen in vitro.
Principle:
2019-nCoV IgM/IgG Antibody Test Kit (colloidal gold method) adopts the indirect immunochromatography technology for the detection. The specimen loaded on the pad will move forward along the nitrocellulose membrane to the detection region as a chromatographic process, with the formation of complexes of SARS-CoV-2 IgM/IgG antibody and colloidal gold labeled SARS-CoV-2 antigen if present. The complexes are captured by anti-human IgG/IgM antibody conjugated in the G and M lines of the nitrocellulose membrane to exhibit the color of purple. In the case of the absence of SARS-CoV-2 IgM/IgG antibody in a specimen, no purple line would be observed in G or M region, while a purple line should always be observed in C region due to the binding of rabbit IgG in the gold label cushion to the goat anti-rabbit antibody in C region, in regardless of the existence of SARS-CoV-2 IgM/IgG antibody in a specimen.
