background CD274, also known as B7-H1 or programmed death ligand 1 (PD-L1), is a 40 kD type I transmembrane protein and a member of the B7 family within the immunoglobulin receptor superfamily. Programmed death-1 ligand-1 (PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. By binding to PD1 on activated T-cells and B-cells, PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly, it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.
description A DNA sequence encoding the N-terminal segment (Met 1-Thr 239) of the extracellular domain of human B7-H1 (NP_054862.1) was produced with a C-terminal His tag.
source HEK293
predicted n terminal Phe 19
AA sequence Met 1-Thr 239
molecular weight The recombinant mature human B7-H1 comprises 232 amino acids and predicts a molecular mass of 26.8 kDa. As a result of glycosylation, the rh B7-H1 migrates as an approximately 35-38 kDa protein in SDS-PAGE under reducing conditions.
purity Greater than 98% as determined by SDS-PAGE
endotoxin < 1.0 EU per μg of the protein as determined by the LAL method
bioactivity Measured by its binding ability in a functional ELISA. Immobilized human B7-H1 at 20 ug/ml (100 ul/well) can bind human PD1 with a linear ranger of 0.032-0.8 ug/ml.
formulation Lyophilized from sterile PBS, pH 7.4
stability Recombinnat Proteins are stable for up to 1 year from date of receipt at -70℃
