SARS-CoV-2 RBD ELISA Kit

PRINCIPLE OF THE ASSAY This assay employs the quantitative sandwich enzyme immunoassay technique. An antibody specific for SARS-CoV-2 RBD has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any SARS-CoV-2 RBD present is bound by the immobilized antibody. After washing away any unbound substances, a biotin-labeled antibody specific for SARS-CoV-2 RBD is added to the wells. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SARS-CoV-2 RBD bound in the initial step. The color development is stopped and the intensity of the color is measured.

Used for the quantitative determination of SARS-CoV-2 RBD concentration in bronchoalveolar lavage fluid and nasopharyngeal swab samples.

When the kit was stored at the recommended temperature for 6 months, the signal intensity decreased by less than 20%.
