PD-1:PD-L2[Biotinylated] Inhibitor Screening Colorimetric Assay Kit Kit-1815

Cat.No.:	Kit-1815
Size:	96 reactions
Description:	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:PDL2[ Biotinylated] Inhibitor Screening Colorimetric Assay Kit is designed for screening inhibitors of PD-L2 ligand binding to PD-1 receptor. The key to this kit is the high affinity of biotin-labeled PD-L2 for 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 a colorimetric HRP substrate to produce color, which can then be measured using a UV/Vis spectrophotometer microplate reader.
Applications:	This kit is most useful for screening for inhibitors of PD1 binding to PD-L2.
Storage:	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.
