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 2 μg/mL (100 μL/well) of Recombinant Human (rh) Klotho beta was immobilized onto a Ms x hKlotho beta coated plate, the concentration of rhFGF-21 that produces 50% of the optimal binding response was found to be approximately 3-18 ng/mL.
