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.

Specificity

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.

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.

Calcium/calmodulin-dependent kinase kinase 2 (CaMKK2) plays a key role in regulating food intake and energy expenditure at least in part by its actions in hypothalamic neurons. Previously, we showed that loss of CaMKK2 protected mice from high-fat diet (HFD)-induced obesity

When fed a standard chow diet, CaMKK2 null mice have increased adiposity and larger adipocytes than do wild-type mice, whereas energy balance is unchanged. Here, we show that Ca(2+)/calmodulin-dependent protein kinase kinase 2 (CaMKK2) is expressed in preadipocytes, where it
