Matrix metalloproteinases (MMPs) 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, which has been implicated in various degenerative disorders, including arthritis, cardiovascular disease, skeletal growth-plate disorders, and cancer metastasis. High levels of MMP-2 are observed in the acute phase of transverse myelitis. It is upregulated in colorectal carcinoma and is associated with poor survival outcome. MMP-2 gene haplotypes are also linked with risk of thoracic aortic dissection, a cardiovascular disorder with high death rate.

General description

Matrix metalloproteinases (MMPs) are a family of endoproteases that require zinc and calcium for expressing catalytic activity. MMP-2 is a secreted collagenase with specificity toward Type IV, V, VII, and X collagens. The gene is mapped to human chromosome 16q12.2. Recombinant human MMP-2 is a 62kDa protein containing the entire catalytic N-terminal domain and the C-terminal domain (552 amino acids).

Physical form

Lyophilized from 10 mM Sodium Phosphate, pH 7.5 + 0.1 mM Calcium Chloride.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
