CD274, Recombinant, Human, aa19-238, His-Tag (Programmed Cell Death 1 Ligand 1, PD-L1, PDCD1 Ligand

CD274, also known as programmed cell death 1 ligand 1(PDCD1L1), is involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. This protein interaction with PDCD1 inhibits T-cell proliferation and cytokine production. Source: Recombinant corresponding to aa19-238 from human CD274, fused to His-tag at N-terminus, expressed in E.coli.
