Bpsbioscience/PD-1[Biotinylated]:PD-L1 Homogeneous Assay Kit/72028/384 reactions

来自 : 发布时间：2025-01-15

Description:The PD-1[Biotinylated]:PD-L1 Homogeneous Assay Kit is designed to measurethe inhibition of PD-1 binding to PD-L1. The PD-1[Biotinylated]:PD-L1 Homogeneous Assay Kitcomes in a convenient AlphaLISA® format with purified biotinylated PD-1, FLAG-tagged PD-L1,and assay buffer to perform a total of 384 reactions. With this kit, only three simple steps on amicrotiter plate are required. First, a sample containing biotinylated PD-1 and an inhibitor ofchoice is incubated with the FLAG-tagged PD-L1 for 60 minutes. Next, acceptor beads areadded, then donor beads, followed by reading the Alpha-counts. Synonym(s): Programmed cell death 1, PDCD1, PD-1, PD1, SLEB2, CD279, HPD-L and Programmed Cell Death 2 Ligand 2, PDL2, PD-L2, CD273, PDCDL1G2, B7-DC Contraindications: Only limited amounts of DMSO can be included, as it has been shownto disrupt PD-1-PD-L1 interaction. Avoid green and blue dyes that absorb light in theAlphaScreen signal emission range (520-620 nm), such as Trypan Blue. Avoid the use of thepotent singlet oxygen quenchers such as sodium azide (NaN3) or metal ions (Fe2+, Fe3+, Cu2+,Zn2+ and Ni2+). The presence of >1% RPMI 1640 culture medium leads to a signal reduction dueto the presence of excess biotin and iron in this medium. MEM, which lacks these components,does not affect AlphaScreen assays. Format:
