一般描述
M.W. 56,000/52,000. Note: 1 mU = 1 milliunit.
Native proMMP-1 from cultured, human rheumatoid synovial fibroblast. Corresponds to the 56 kDa/52 kDa enzyme. May contain some activated enzyme but requires activation by APMA (Cat. No. 164610) for 30 - 60 min. at 30°C just prior to use to obtain fully activated enzyme (46 kDa/42 kDa). May also undergo autocatalysis to yield a 27 kDa/22 kDa active enzyme. Expressed by a large number of cell types. Cleaves fibrillar type I collagen.

Studies in our laboratory indicate that collagenase from Clostridium histolyticum promotes endothelial cell and keratinocyte responses to injury in vitro and wound healing in vivo. We postulate that matrix degradation by Clostridial collagenase creates bioactive fragments that can stimulate cellular
