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

Measured by its binding ability in a functional ELISA. When Recombinant Human (rh) SIRP alpha/CD172a Fc Chimera (Catalog # 4546-SA ) is coated at 2 μg/mL, Recombinant Human CD47 Fc Chimera binds with an apparent Kd <1 nM.

Optimal dilutions should be determined by each laboratory for each application.

Also measured by its ability to antagonize red blood cell adhesion to immobilized rhSIRP alpha Fc Chimera. The ED50 for this effect is 0.5-2.0 μg/mL.
