Background:
Programmed Death-Ligand 1 (PD-L1), a 40KD transmembrane protein, is a ligand of immune checkpoint protein Programmed Death-1 (PD-1). During T-cell receptor signalling, the binding of PD-L1 to PD-1 transmits an inhibitory signal to activated T-cells to decrease their proliferation. PD-L1 is also believed to play a role in the generation and regulation of Treg cells, and in the enhancement of Treg cell function. PD-L1/PD-1 pathway is important to immune suppression, such as self-tolerance, suppression of immune-rejection during pregnancy and allograft, and immune evasion by cancers. Upregulation of PD-L1 has been found to be associated with many cancer types. For example, increased PD-L1 expression has been shown to be related to tumor aggressiveness and higher mortality in patients with renal cell carcinoma, and related to significantly poorer prognosis and lower intraepithelial CD8+ T-lymphocyte count in patience with ovarian cancer. Antibodies that block the PD-L1 /PD-1 pathway have been extensively studied in clinical trials, and some have been approved as immunotherapy for cancer.
Applications:
ELISA: Indirect ELISA: The antibody reacts with recombinant PD-L1 in indirect ELISA.
Western blot: Western Blot: Anti-PD-L1 clone 15F2 detected 40ng recombinant PDL-1 on Western Blot. The blot was stained with HRP substrate 4-Chloro-1-Naphthol.
