Our PD-L1 (Extracellular region) mouse monoclonal primary antibody from PhosphoSolutions is produced in-house. It detects human PD-L1 (Extracellular region) and is Protein G purified. It is great for use in WB, ICC, IP.
Western blot of human recombinant PD-L1 extracellular region (40 kDa; lanes 1 & 3) and endogenous PD-L1 in human lung (lanes 2 & 4). The blot was probed with mouse monoclonals anti-PD-L1 (PM0511) at 1:500 (lanes 1 & 2) and anti-PD-L1 (PM0801) at 1:250 (lanes 3 & 4).
Programmed cell death 1 ligand 1 (PD-L1, B7-H1, CD274) is a member of the B7 family of cell surface ligands that regulate T cell activation and immune responses. The B7 family members have conserved regions that include extracellular IgV and IgC domains, and a short cytoplasmic region. Research studies demonstrate that PD-L1 is expressed in several tumor types, including melanoma, ovary, colon, lung, breast, and renal cell carcinomas. PD-L1 plays a critical role in induction and maintenance of immune tolerance to self. As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response. The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, which promotes tumor survival. The blockage of the PD1/PD-L1-mediated pathway results in the reversal of the exhausted T-cell phenotype and the normalization of the anti-tumor response, providing a rationale for cancer immunotherapy. Several therapies that target PD1/PD-L1 pathways are currently in use or in clinical trials
