Recombinant Human Programmed cell death 1 ligand 1 (CD274) ,partial (Active) | CSB-MP878942HU1 | Cusabio

Protein Description: Partial

Alternative Name (s) : PD-L1 (PDCD1 ligand 1) (Programmed death ligand 1) (hPD-L1) (B7 homolog 1) (B7-H1) (CD274)

Gene Names: CD274

Research Areas: Cancer

Species: Homo sapiens (Human)

Source: Mammalian cell

Tag Info: C-terminal hFc-tagged

Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized PD-L1 at 2 μg/ml can bind Anti- PD-L1 mouse monoclonal antibody (CSB-MA878942A1m,antigen from E.coli) , the EC50 of human PD-L1 protein is 1.252-1.653 ng/mL.

MW: 52.7 kDa

Purity: Greater than 95% as determined by SDS-PAGE.

Endotoxin: Less than 1.0 EU/ug as determined by LAL method.

Relevance: Plays a critical role in induction and maintenance of immune tolerance to self (PubMed:11015443, PubMed:28813417, PubMed:28813410) . As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response (PubMed:11015443, PubMed:28813417, PubMed:28813410) . Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10) (PubMed:10581077) The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival (PubMed:28813417, PubMed:28813410) . The interaction with PDCD1/PD-1 inhibits cytotoxic T lymphocytes (CTLs) effector function (By similarity) . The blockage of the PDCD1-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 (By similarity) .

Form: Lyophilized powder

Buffer: Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
