Principiul testului

Human SARS-CoV-2 (N) IgG ELISA Kit (A326999) employs an indirect Enzyme-Linked Immunosorbent Assay (ELISA) technique for the qualitative detection of human SARS-CoV-2 (N) IgG in serum and plasma. The microtiter plate provided in this kit has been pre-coated with purified SARS-CoV-2 (N) IgG antigen. Following addition of standards and test samples to the wells, SARS-CoV-2 (N) IgG antibodies present in the sample bind to the immobilized antigen. Following incubation and washing, HRP-conjugated secondary antibody working solution is added to develop the antigen-antibody-secondary antibody immune complex. Following a further washing step to remove unbound components, TMB substrate solution is added to each well to visualize the HRP enzymatic reaction, producing a blue-coloured product that changes to yellow following addition of acidic stop solution. The optical density (O.D.) is measured spectrophotometrically at 450 nm. Sample results are interpreted by comparison with the cut-off value to determine the presence or absence of SARS-CoV-2 (N) IgG antibodies in the tested samples.
