Background
Matrix metalloproteinases (MMPs) are a family of endoproteases that require zinc and calcium for expressing catalytic activity. These enzymes play a central role in the maintenance and remodeling of the extracellular matrix. Elevated expression of their activity, caused either by up-regulation of their expression or down-regulation of their cognate inhibitors, has been implicated in various degenerative disorders, including arthritis, cardiovascular disease, skeletal growth-plate disorders, and cancer metastasis. MMP-3 degrades fibronectin, laminin, collagens III, IV, and X, and cartilage proteoglycans. Recombinant human MMP-3 is a 42.8 kDa protein containing the entire catalytic N-terminal domain and the C-terminal domain (378 amino acids).
Specifications
Additional Names
Stromelysin-1, SL-1, Transin-1, Matrix metalloproteinases
Purity
Greater than 98% by SDS-PAGE gel and HPLC analyses.
Endotoxin level is less than 0.1 ng per μg (1EU/μg).
Species Reactivity

Storage
The lyophilized MMP-3 recombinant protein is stable for at least 2 years from date of receipt at -20ËšC. Reconstituted MMP-3 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20ËšC. As with any protein, exposing MMP-3 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
Tested Application

Preparation
MMP-3 activity was measured by its ability to cleave a chromogenic peptide MMP-3 substrate at room temperature. At a MMP-3 concentration of 2.5 μg/mL, 50% cleavage was achieved at an incubation time of approximately 75 minutes.
