Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM MES buffer (pH 5.5) containing 10mM CaCl2, 100 mM NaCl, 0.05% Brij35, 30% glycerol.. MMP1, also known as interstitial collagenase isoform 1, contains 4 hemopexin-like domains and is a member of the matrix metalloproteinase (MMP) family. It is capable of degrading a wide range of extracellular molecules and a number of bioactive molecules. It plays a central role in cell proliferation, migration, differentiation, angiogenesis, apoptosis and host defences. Recombinant human MMP1, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
