PD-1 : PD-L1 [Biotinylated] Inhibitor Screening ELISA Kit

Immune checkpoint pathway is a focal point of today’s cancer research. PD-1 is one of the best characterized checkpoint proteins. The binding between PD-1 and its ligand PD-L1 suppresses T-cell activation and allows cancer cells to escape from body’s immune surveillance. Therefore, the pharmaceutical inhibition of PD-1 or its ligand has been considered a promising strategy by many oncologists.

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-L1 to immobilized human PD-1 in a functional ELISA assay, and employs a simple colorimetric ELISA platform. Briefly, we provide you with a human Biotinylated PD-L1 protein, a human PD-1 protein, an anti-PD-1 neutralizing antibody (as method verified Std.), and Streptavidin-HRP reagent.
