Catalog No.	Quantity
85-84O-X050	50 μg

Catalog No. 85-84O-X050 Supplier R&D Systems™ Supplier No. 8584OX050

Description

Extensive quality control produces industry leading bioactivity and lot-to-lot consistency that instills confidence in results and ensures reproducibility.

Measured by its binding ability in a functional ELISA. When recombinant rat OX40 Ligand is coated at 75 ng/mL (100 μL/well), the concentration of Recombinant OX40 Fc Chimera that produces 50% optimal binding response is 1-5 ng/mL.
