The Spike S1 (B.1.1.7 Variant) (SARS-CoV-2): ACE2 Inhibitor Screening Chemiluminescence Assay Kit is designed for screening and profiling inhibitors of the interaction of ACE2 with the B.1.1.7 Variant of the SARS-CoV-2 Spike S1 protein. The key to this kit is the high sensitivity of detection of ACE2-Biotin protein by Streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, Spike S1 B.1.1.7 protein is coated on a 96-well transparent plate. Next, ACE2-Biotin is incubated with Spike S1 variant on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can then be measured using a luminometer or microplate reader capable of reding chemiluminescence.
