• Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human PD-L1 Fc
• Anti-Human PD-L1 Fc-specific antibody was purified by affinity chromatography employing an immobilized Human PD-L1 Fc matrix
• Sandwich ELISA: To detect Human PD-L1 Fc by sandwich ELISA (using 100 μL/well), a concentration of 0.5-2.0 μg/mL of this antibody is required
• This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human PD-L1 Fc (500-P321BT) as a detection antibody, allows the detection of at least 2000-4000 pg/mL of Recombinant Human PD-L1 Fc
• Western Blot: To detect Human PD-L1 Fc by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL
• When used in conjunction with compatible secondary reagents, the detection limit for Recombinant Human PD-L1 Fc is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions
• 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.
