Elsi COVID**9 antigen kit uses a double antibody sandwich method to detect the antigen of the novel coronavirus (SARS-CoV*2) in nasopharyngeal swab samples. During detection, the gold-labeled antiSARS-CoV*2 monoclonal antibody on the labeling pad binds to the SARS-CoV*2 antigen in the sample and forms a complex. The reaction complex then moves forward across the nitrocellulose membrane under the influence of chromatography and captured by the anti-SARS-CoV*2 monoclonal antibody pre-coated by the detection zone (T) on the membrane. If the sample does not contain the SARS-CoV*2 antigen, a red colored reaction line cannot form in the T region. Regardless of whether the sample to be tested contains the SARS-CoV*2 antigen, a red colored reaction line will always appear in the quality control area (C).
