详细信息:MMP-3, human, proform.Purified MMP-3 (EC3.4.24.17) is a matrix metalloproteinase purified from human fibroblast cell culture media. The stromelysin is free of its endogenous inhibitors, TIMP-1 and TIMP-2, and other matrix metalloproteinases. The zymogen runs as 59 and 57 kDa bands, representing the glycosylated and non-glycosylated forms. Active enzyme runs at 45 kDa and breaks down stepwise to a 28 kDa form
