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

• Cat.No.: Kit-1820

Specification

• 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[Biotinylated]:PD-L2 Inhibitor Screening Colorimetric Assay Kit is designed for screening inhibitors of PD-1 receptor binding to PD-L2 ligand. The key to this kit is the high affinity of biotin-labeled PD-1 for streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, PD-L2 is coated on a 96-well plate. Next, PD-1 is incubated with PD-L2 on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of a colorimetric HRP substrate 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 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.
