SARS-CoV-2 IgM/IgG Antibody Assay Kit (Immunochromatography)

serum, plasma, whole blood or fingertip blood

This product adopts colloidal gold immunity technology, the gold marker of recombinant SARS-CoV-2 antigen and control antibody was sprayed on the binding pad; The nitrocellulosic membrane is coated with two test lines (G and M) and a control line (C). The M-line was coated with mouse anti-human IgM monoclonal antibody, which was used to detect the SARS-CoV-2 IgM antibody; The G-line was coated with mouse anti-human IgG monoclonal antibody, which is used to detect the SARS-CoV-2 IgG antibody. The C-line was coated with a quality control antibody. When the SARS-CoV-2 sample is added to the sample hole of the test card, the sample will move along the test card under the action of chromatography. If the sample contains the SARS-CoV-2 IgM antibody, the antibody binds to the goldlabeled virus antigen. The immune complex forms a sandwich complex with the coated mouse anti-human IgM monoclonal antibody at the M line, showing a purplish red M line, indicating a positive IgM antibody for the novel coronavirus. If the sample contains the SARS-CoV-2 IgG antibody, they bind to the gold-labeled SARS-CoV-2 antigen. The immune complex forms a sandwich complex at the G line with the coated mouse anti-human IgG monoclonal antibody, showing a purplish red G line, indicating that the SARS-CoV-2 IgG antibody is positive. If the test line G and M do not produce color, the negative result is displayed. The test card also contains a control line C. The purplish red control line C should be present regardless of whether there is a test line. If the control line C does not appear, it indicates that the test result is invalid, and the sample should be tested again.
