Merck, 11213857001, Collagenase P

General description
Collagenase P is an enzyme mixture prepared from the extracellular culture filtrate of a special Clostridium histolyticum strain.Collagenase P is a research biochemical, not manufactured under the US good manufacturing practices (GMP) regulations.
Note: Collagenase P is a non-sterile preparation of the culture supernatant of Clostridium histolyticum. It is neither designed nor intended for isolation of pancreatic islets for transplantation into humans and must not be used for such purposes.
Application
Collagenase from C. histolyticum is used for the dissociation of tissues for the establishment of primary cell cultures. Because of its high collagenase activity Collagenase P is particularly suitable for the isolation of pancreatic islets from mouse and rat (function tested). The preparation is also suitable for the isolation of adipocytes from epididymal fat pads of rats.
Biochem/physiol Actions
Enzyme activity:
Collagenase activity: >1.5U/mg (according to Wünsch) (+25°C, 4-phenyl-azobenzyl-oxycarbonyl-Pro-Leu-Gly-Pro-D-Arg as the substrate)
Contaminating enzyme activities: trypsin, clostripain, and total proteolytic activity
Collagenase P has a very high collagenase activity (>1.5U/mg), and is function tested for the isolation of mouse pancreatic islets.
Specificity: Collagenase degrades native collagen. Clostripain, trypsin-like enzymes, and neutral proteases degrade other proteins as well.
