PD-L1, Human (221a.a, HEK293, Fc)

The PD-L1 protein critically regulates immune tolerance by acting as a ligand for PDCD1/PD-1, regulating T cell activation threshold, and limiting effector responses. It may act as a costimulatory molecule for IL10-producing T cell subsets. PD-L1 Protein, Human (221a.a, HEK293, Fc) is the recombinant human-derived PD-L1 protein, expressed by HEK293 , with C-hFc labeled tag.
