PD-1 [Biotinylated] : PD-L2 Inhibitor Screening ELISA Kit

PD-L2, also known as CD273 or B7-DC, is a member of the B7 family protein with PD-L1, and it is the second important ligand that can bind pD-1 after PD-L1. The human PD-L2(B7-H2, CD273) gene is also located on chromosome 9p24, encoding type I transmembrane protein with 247 amino acids. The homology of PD-L1 and PD-L2 was 40%. The affinity between PD-L2 and PD-1 is 2-6 times that of PD-L1. Compared with PD-L1, the expression of PD-L2 is relatively limited, and pD-L2 is induced to express on the surface of dendritic cells, macrophages, bone marrow derived mast cells and other cells.

1. Unopened kit should be stored at 2°C-8°C upon receiving. 2. Find the expiration date on the outside packaging and do not use reagents past their expiration date. 3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

This inhibitor screening ELISA kit is designed to facilitate the identification and characterization of new PD-1 pathway inhibitors. The assay takes advantage of our in house-developed binding of biotinylated human PD-1 to immobilized human PD-L2 in a functional ELISA assay, and employs a simple colorimetric ELISA platform. Briefly, we provide you with a human Biotinlated PD-1 protein, a human PD-L2 protein, an anti-PD-1 neutralizing antibody (as method verified Std.), and Streptavidin-HRP reagent.
