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 OX40/TNFRSF4 Fc Chimera is immobilized at 10 ng/mL, the concentration of Recombinant Human OX40 Ligand/TNFSF4 (Catalog # 1054-OX ) that produces 50% optimal binding response is found to be approximately 0.5-3 ng/mL.
