          PD-L1 Antibody (PA5-20343) in ICC/IF

          Immunofluorescence analysis of CD274 was performed using log phase THP-1 cells treated with PMA (200 ng/mL, 6 hours), IFN gamma (20 ng/mL) and LPS (100 ng/mL), 18hours. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with PD-L1 Polyclonal Antibody (Product # PA5-20343, 1:100 dilution) in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly C...

          Product Specific Information

          This antibody detects human PD-L1 isoform 1 (290aa, 33.3 kDa) and isoform 3 (178aa, 20.5 kDa), as well as mouse and rat PD-L1 (290aa, 33 kDa). It will not cross-react with PD-L2. By Western blot, this antibody has been observed to detect a band at 37 kDa.

          Recommended positive controls: HeLa cell lysate, Daudi cell lysate, K562 cell lysate, human heart tissue/lysate.

          PA5-20343 can be used with blocking peptide PEP-0463.

          The PA5-20343 immunogen is located within amino acids 60-110 of PD-L1.

          Target Information

          Programmed death receptor ligand 1 (PD-L1, also called B7-H1) is a recently described B7 family member. To date, one specific receptor has been identified that can be ligated by PD-L1. This receptor, programmed death receptor 1 (PD-1), has been shown to negatively regulate T-cell receptor (TCR) signaling. Upon ligating its receptor, PD-L1 has been reported to decrease TCR-mediated proliferation and cytokine production. PD-L1 expression was found to be abundant on many murine and human cancers and could be further up-regulated upon IFN-gamma stimulation. Thus, PD-L1 might play an important role in tumor immune evasion.
