Matrix metalloproteinases are a family of zinc and calcium dependent endopeptidases with the combined ability to degrade all the components of the extracellular matrix. MMP‑2 (gelatinase A), a type IV collagenase, can degrade a broad range of substrates including type IV, V, VII and X collagens as well as elastin and fibronectin. It is believed to act synergistically with interstitial collagenase (MMP‑1) in the degradation of fibrillar collagens as it degrades their denatured gelatin forms. MMP‑2 has been shown to be associated with many connective tissue cells as well as neutrophils, macrophages and monocytes. Structurally, MMP‑2 may be divided into several distinct domains: a pro-domain which is cleaved upon activation; a catalytic domain containing the zinc binding site; a fibronectin-like domain thought to play a role in substrate targeting; and a carboxyl terminal (hemopexin-like) domain containing 2 N-linked glycosylation sites.

FAQs for Recombinant Human MMP-2 (NS0-expressed) Protein, CF
-
Q: Can the enzyme be stored after activation, or do I need to use it immediately after activation?
A: We recommend only activating the amount of enzyme needed for your assay, and recommend activating the enzyme immediately prior to use. Any unactivated enzyme should be stored in aliquots at either the stock concentration at which the enzyme was supplied, or the reconstitution concentration, according to the product datasheet.
-
Q: Does this enzyme have a tag?
A: No, this enzyme does not have a tag. Please refer to the Source section on the product-specific page or product datasheet for sequence information.
-
Q: Does this MMP enzyme need to be activated to work?
A: Yes, this enzyme requires activation prior to use.
-
Q: If I use this enzyme at a higher concentration, do I need to change the concentration of APMA to activate it?
A: We have only optimized activation conditions for one particular concentration of this MMP enzyme as part of our regular QC testing for enzymatic activity. Activating the enzyme at any different concentration would have to be optimized by the end user.
-
Q: What is the activity of this enzyme in units/µg?
A: We supply this enzyme as a mass and calculate its activity relative to mass (pmol/min/µg). We have not calibrated this enzyme to an international standard unit, so we are unable to provide a conversion to units/µg.
