||Cell signaling through the PD-1 receptor upon binding the PD-L2 ligand attenuates immune responses and is exploited by both tumors and viruses.
||The PD-1:PD-L2[Biotinylated] Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of this signaling. The key to this kit is the high sensitivity of detection of biotin-labeled PD-L2 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, PD-1 is coated on a 96-well plate. Next, PD-L2 is incubated with PD-1 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 chemiluminescence reader.
||This kit is useful for screening for inhibitors of PD1 binding to PD-L2.
||Stable at least 6 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival.
