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.

Preparation Note

Activator: Ca²⁺
Inhibitors:
Collagenase inhibitors: EDTA, EGTA, Cys, His, DTT, 2-mercaptoethanol
Collagenase is not inhibited by serum.
Clostripain inhibitors: TLCK
Trypsin inhibitors: aprotinin, trypsin inhibitor (egg white, soybean)
Working concentration: 0.5 to 2.5mg/ml
0.5 to 1.5mg/ml for the isolation of pancreatic islets from mouse and rat pancreas.
Approximately 2mg/ml for the isolation of adipocytes.
Storage conditions (working solution): -15 to -25°C
The reconstituted solution is stable at -15 to -25°C. Prepare appropriate aliquots and avoid repeated freezing and thawing.

Reconstitution

Reconstitution in any balanced salt solution (e.g., HBSS)

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).^[3] The preparation is also suitable for the isolation of adipocytes from epididymal fat pads of rats.^[1][2]
