R&D Systems™ Recombinant Human Protein S/PROS1

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 Human Tyro3/Dtk Fc Chimera (Catalog # 859-DK ) is immobilized at 1 μg/mL, 100 μL/well, Recombinant Human Protein S/PROS1 binds with an ED50 of 0.2-1.2 μg/mL.
