| Cat.No. : | Kit-1811 |
| Size : | 96 reactions |
| Description : | Cell signaling through the PD-1 receptor upon binding the PD-L1 ligand attenuates immune responses and is exploited by both tumors and viruses. The PD-1:PDL1[Biotinylated] Inhibitor Screening Colorimetric Assay Kit is designed for screening inhibitors of PD-L1 ligand binding to PD-1 receptor. The key to this kit is the high affinity of biotin-labeled PD-L1 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-L1 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 useful for screening for inhibitors of PD-1 binding to PD-L1. |
| 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. |
