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-1 is a secreted collagenase with specificity toward Type I, II, III, VII, and X collagens. Recombinant human MMP-1 is a 42.7 kDa protein containing the entire catalytic N-terminal domain and the C-terminal domain which is involved in substrate specificity and in binding TIMP-1.

Additional Names
Matrix metalloproteinase-1; Fibroblast collagenase; interstitial collagenase
Preparation
MMP - 1 activity was measured by its ability to cleave a chromogenic peptide MMP - 1 substrate at room temperature. At an MMP - 1 concentration of 2.5 μg/ml, 50% cleavage was achieved at an incubation time of approximately 25 minutes

Storage
The lyophilized MMP-1 recombinant protein is stable for at least 2 years from date of receipt at -20ËšC. Reconstituted MMP-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20ËšC. As with any protein, exposing MMP-1 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.
