Notes
Activation: This is a proform enzyme andrequires activation prior to testing activity. Dilutethe enzyme to 100 ng/ml in a solution containing50 mM HEPES, pH 7.4, 10 mM CaCl2, 0.05%Brij-35, and 1 mM APMA (amino-phenylmercuric acetate). Incubate at 37°C for 2 hours. Assay conditions: Reaction mixture with 10 uM390 MMP substrate 1 (Anaspec). Incubate for30 minutes at room temperature. Fluorescenceintensity is measured at exc328/em393.
