Allgemeine Beschreibung

Collagenase H is an enzyme mixture prepared from Clostridium histolyticum cultures by filtration, ammonium sulfate precipitation, dialysis, and lyophilization.

Spezifität

Collagenase degrades native collagen. Clostripain, trypsin-like enzymes, and neutral proteases also degrade other proteins.

Anwendung

Collagenase from C. histolyticum is used for the dissociation of tissues for the establishment of primary cell cultures. Collagenase H is well suited for the isolation of hepatocytes from rat liver by the collagenase perfusion method. This enzyme preparation is also suitable for the preparation of other types of cells such as endothelial cells from large vessels, and for the isolation of adipocytes from epididymal fat pads of rats.

Physikalische Form

Lyophilizate, nonsterile

Angaben zur Herstellung

Enzyme activity:
Collagenase activity: >0.15U/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 H has a balanced ratio of enzyme activities, and is function tested for the isolation of rat hepatocytes (perfusion method).
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)
Activator: Ca2+
Working concentration: 0.5 to 2.5mg/ml,
Approximately 1 mg/ml for the isolation of rat hepatocytes and 2mg/ml for the isolation of adipocytes.
Storage conditions (working solution): -15 to -25°C
The reconstituted solution should be stored at -15 to -25°C for short term storage, -60°C or as described below for long-term storage.

Rekonstituierung

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

Lagerung und Haltbarkeit
