Product overview
COVID-19 S-Protein (S1RBD) Human IgA ELISA Kit (ab276185) is an in vitro indirect ELISA for the quantitative measurement of human IgA antibody against SARS-CoV-2 S1 RBD protein in human serum.
Standard 96-well plates (12 strips with 8 wells/strip) are coated with the SARS-CoV-2 S1 RBD protein, which combines with the corresponding antibody present in a sample and Positive control, which used as calibration curve for interpretation purposes. The wells are washed, and biotinylated anti-human IgA antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells, and color develops in proportion to the amount of COVID19 S1 RBD protein human IgA antibody bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
The Positive Controls are from an inactivated serum sample which contains SARS-COV-2 S1 RBD protein human IgA antibody. We do not know the exact amount of SARS-COV-2 S1 RBD protein human IgA antibody in the Positive Control sample. The Positive Control can be used as a calibration curve for interpretation purposes in different assays.
