背景资料 | Programmed death-ligand 1 (PD-L1), also known as CD274 or B7-H1, is a protein that in humans is encoded by the CD274 gene. It is mapped to 9p24.1. PD-L1 is a 40kDa type 1 transmembrane protein that has been speculated to play a major role in suppressing the immune system during particular events such as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis. It has been concluded that upregulation of PD-L1 on tumor MDCs downregulates T-cell immunity and that PD-L1 blockade may represent an approach for cancer immunotherapy. Additionally, PD-L1 can provide positive costimulatory signals for innate and adaptive immunity and for protection against intracellular bacterial infection. What’s more, it has been found that PD1/PDL1 pathway may be a good target for restoring antitumor immunity in ovarian cancer. |

[list_product_images]Figure 1. Western blot analysis of PD-L1/B7-H1 using anti-PD-L1/B7-H1 antibody (A00109). The sample well of each lane was loaded with 50ug of sample under reducing conditions. Lane 1: HELA whole cell lysates.-PD-L1/B7-H1 antigen affinity purified polyclonal antibody (Catalog # A00109) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody . The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) A specific band was detected for PD-L1/B7-H1 at approximately 40-45KD. The expected band size for PD-L1/B7-H1 is at 33KD.[/list_product_images]
