    This COVID19 human IgG antibody ELISA kit employs an indirect ELISA method. In this kit, standard 96-well plates (12 strips with 8 wells/strip) are coated with the SARS-CoV-2 S protein, which combines with the corresponding antibody present in a sample and Positive Control which used as calibration curve for normalization purpose. The wells are washed and biotinylated anti-human IgG 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 S protein human IgG antibody bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
    Assay Procedure
    1. Prepare all reagents, samples and standards as instructed.
    2. Add 100 µl positive control or sample to each well. Incubate 1 hour at room temperature.
    3. Add 100 μl prepared Biotinylated Anti-Human IgG Antibody into each well. Incubate 30 minutes at room temperature.
    4. Add 100 μl prepared HRP-Streptavidin solution to each well. Incubate 30 minutes at room temperature.
    5. Add 100 µl TMB One-Step Substrate Reagent to each well. Incubate 15 minutes at room temperature.
    6. Add 50 µl Stop Solution to each well. Read at 450 nm immediately.
