Biological Activity: Specific activity is > 15,000 pmol/min/ug in which one unit defined as the amount of enzyme that hydrolyze 1pmole of H-Gly-Pro-AMC.HBr to H-Gly-Pro and AMC per minute at pH 8.0 at 37°C. The ED50 range 250 ng/ml is measured by its binding ability in a functional ELISA with MERS-CoV Spike S1 Subunit.. The ED50 range 200 ng/ml is measured by its binding ability in a functional ELISA with MERS-CoV Spike RBD. The ED50 range 120 ng/ml is measured by its binding ability in a functional ELISA with MERS-CoV Spike
