Formulation
The MMP-2 is supplied as a 0.2µm filtered solution in 20mM Tris-HCl, 150mM NaCl and 0.05% Brij 35, pH 7.4.
Purity
Greater than 95% as determined by SDS-PAGE.
Biological Activity
The activity was measured by its ability to cleave fluorogenic peptide substrate, Mca-PLGL-Dpa-AR-NH2 (RND,Catalog # ES001)., The specific activity is > 1,000 pmoles/min/µg.
Recombinant Human MMP-2 protein pro form needs to be activated with p-aminophenylmercuric acetate (APMA).
Activation Protocol:
1. Dilute MMP2 to 100µg/ml in the Assay Buffer: 50mM Tris, 10mM CaCl2, 150mM NaCl, 0.05% (w/v) and Brij 35, pH 7.5.
2. Activate MMP2 by adding APMA to a final concentration of 1mM. (Sigma, Catalog # A9563) and 100mM stock in DMSO.
3. Incubate at 37°C for 1 hour.
