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 Fc epsilon RI alpha is immobilized at 0.1 μg/mL (100 μL/well), the concentration of human IgE that produces 50% of the optimal binding response is found to be approximately 0.0200-0.200 μg/mL.
