Description

General description

Dimeric, native MMP-9 from stimulated human neutrophils. Enzyme should be activated just prior to use.

M.W. 222,000 (non-reducing SDS-PAGE). Note: 1 mU = 1 milliunit.

Warning

Toxicity: Standard Handling (A)

Unit Definition

One unit is defined as the amount of enzyme that will hydrolyze 1.0 µmol 2,4-DNP-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg-OH per min at 37°C pH 7.0.

Physical form

In 200 mM NaCl, 50 mM Tris-HCl, 5 mM CaCl₂, 1 µM ZnCl₂, 0.05% BRIJ^® 35 Detergent, 0.05% NaN₃, pH 7.0.

Preparation Note

Prepared from stimulated neutrophils that have been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.

Reconstitution

Following initial thaw, aliquot and freeze (-70°C).
