The product CSB-E04672h is an in vitro ELISA kit quantitatively measuring the content of Human Matrix metalloproteinase 1 (MMP-1) in serum, plasma, cell culture supernates, or tissue homogenates. MMP-1 is one of the MMPs, which are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in pathogenetic processes of some diseases, including arthritis and metastasis. Specifically, MMP-1 digests the interstitial collagens, types I, II, and III. It can be released by several cells, including fibroblasts, macrophages, and endothelial cells. Its expression is associated with inflammation, wound healing, and tumor invasion, growth, and metastasis. The involvement of MMP-1 during development as well as in the maintenance, repair, and regeneration of several tissues and organs has been reported. Moreover, it has been shown that intracellular MMP-1 in platelets activates pathways that sign.
