SARS-CoV-2 RBD ELISA Kit

This SARS-CoV-2 RBD ELISA Kit (ab289833, E4877) is designed to quantitatively measure the amount of RBD protein in bronchoalveolar lavage fluid and nasopharyngeal swab samples. The assay is based on the Sandwich ELISA principle. Test samples, Standards, and Detection A solution are added to the wells pre-coated with the RBD antibody and then washed with Wash Buffer. The Detection B solution is added and any unattached conjugates are washed off using Wash Buffer. The enzymatic reaction is detected by the addition of TMB-substrate. Finally, the reaction is terminated with an acidic stop solution. The color developed is proportional to the concentration of RBD in the sample or standard.
