Sandwich ELISA quantitative detection kit for Human MMP-1 in cell culture supernates, serum and plasma (heparin).Matrix metalloproteinase-1 (MMP-1) is also known as collagenase. Matrix metalloproteinases (MMPs) are zinc-dependent proteases that degrade extrMMP-1llular matrix proteins. The MMPs comprise a family of at least 20 proteolytic enzymes that play an essential role in tissue remodeling. Matrix metalloproteinase-1 (MMP-1) plays an important role in the degradation of collagen in inflammatory diseases.1 MMP1 (interstitial collagenase), MMP9 (gelatinase B) and MMP12 (macrophage elastase) are thought to be important in the development of emphysema.2 Smoking-induced MMP-1 might be important in the skin-ageing effects of tobacco smoking.3 The standard product used in this kit is human MMP-1 with the molecular mass of 51-53kD. The detected MMP-1 includes zymogen and active enzyme.
