Merck, 444208-100UG, MMP-1, Proenzyme, Human Rheumatoid Synovial Fibroblast

General description
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.
Packaging
Please refer to vial label for lot-specific concentration.
