Description

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

Measured by its binding ability in a functional ELISA. When Recombinant SARS-CoV-2 Spike RBD Fc Chimera (Catalog # 10499-CV ) is immobilized at 0.2 μg/mL (100 μL/well), Recombinant Human ACE-2 (Catalog # 933-ZN) binds with an ED50 of 1.00-12.0 ng/mL. Measured by its ability to cleave a fluorogenic peptide substrate, Mca-YVADAPK(Dnp)-OH (Catalog # ES007 ). The specific activity is >800 pmol/min/μg, as measured under the described conditions.
