Innovative Research Inc Covid IgG Seroconversion Kit
SARS-CoV-2 IgG Seroconversion ELISA Kit - This ELISA from Innovative Research is intended for the qualitative determination of SARS-CoV-2 specific antibodies of IgG class in plasma or serum samples. Strip well format for up to 96 tests. RUO. This assay has been specifically developed using the SARS-CoV-2 receptor binding domain (RBD) of the spike protein. This assay can be performed in 70 minutes, and has an overall sensitivity of 97-100% and specificity of 100%. Principle of the Assay SARS-CoV-2 specific antibodies will bind to the purified recombinant HEK cell derived receptor-binding domain (RBD) of the SARS-CoV-2 spike protein coated on the microtiter plate. After appropriate washing steps, horseradish peroxidase labeled polyclonal anti-human IgG secondary antibody binds to the captured protein. Excess secondary antibody is washed away and TMB substrate is used for color development at 450 nm. Samples that exceed a determined cut-off value are designated positive by this assay.
