Description

Extensive quality control produces lot-to-lot consistency that instills confidence in results and ensures reproducibility. Applications: Binding Activity

Measured by its binding ability in a functional ELISA. When Recombinant Human PD-L1/B7-H1 is immobilized at 0.025 μg/mL (100 μL/well), the concentration of Recombinant Human PD-1 Fc Chimera (Catalog # 1086-PD ) that produces 50% of the optimal binding response is approximately 0.05-0.3 μg/mL.
