CTLA4:B7-1[Biotinylated] Inhibitor Screening Assay Kit

The CTLA4:B7-1[Biotinylated] Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of CTLA4:B7-1 signaling. The key to this kit is the high sensitivity of detection of biotin-labeled B7-1 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, CTLA4 is coated on a 96-well plate. Next, B7-1 is incubated with CTLA4 on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can be measured using a chemiluminescence reader.
