General description
M.W. 56,000/52,000. Note: 1 mU = 1 milliunit.
Native proMMP-1 from cultured, human rheumatoid synovial fibroblast. Corresponds to the 56 kDa/52 kDa enzyme. May contain some activated enzyme but requires APMA (Cat. No. 164610; 30-60 minutes at 37°C, just prior to use) to obtain fully activated enzyme (46 kDa/42 kDa). May also undergo autocatalysis to yield a 27 kDa/22 kDa active enzyme. Expressed by a large number of cell types. Cleaves fibrillar Type I collagen. Must be activated just prior to use.

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 300 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 culture medium of human rheumatoid synovial fibroblasts that has 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).

Matrix metalloproteinases (MMPs) are a family of endopeptidases capable of degrading extracellular matrix (ECM) components. They are known to play crucial roles during the ECM turnover in both physiological and pathological processes. As such, their activities are utilized as biological

Studies in our laboratory indicate that collagenase from Clostridium histolyticum promotes endothelial cell and keratinocyte responses to injury in vitro and wound healing in vivo. We postulate that matrix degradation by Clostridial collagenase creates bioactive fragments that can stimulate cellular
