Applicazioni

Collagenase has been used in the preparation of arterial tissue for the study of Advanced Glycosylation End Products (AGE). The enzyme has also been used along with other proteases for the disaggregation of human tumor, mouse kidney, human brain, lung epithelium and many other tissues. It is also used for liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes. This enzyme is tested for the release of hepatocytes at approx.1 mg/mL conc. (in a total volume of 100 mL for each rat liver).

Azioni biochim/fisiol

Effective release of cells from tissue requires the action of collagenase enzymes and the neutral protease. Collagenase is activated by four gram atom calcium (Ca2+) per mole enzyme. The culture filtrate is thought to contain at least 7 different proteases ranging in molecular weight from 68-130 kDa. The pH optimum is 6.3-8.8. The enzyme is typically used to digest the connective components in tissue samples to liberate individual cells. Collagenase treatment can cause some cells to die. Typically, concentrations varying from 0.1 to 5 mg/mL are used for digestion. The duration of reaction varyies from 15 minutes to several hours and yields a satisfactory cell dissociation without causing too much cell death. Krebs Ringer buffer with calcium and BSA is preferred and Zn2+ is required for activity.
La collagenasi è attivata da quattro grammi atomo di calcio per mole di enzima. È inibita da etilen-glicol-bis(beta-amminoetil etere) - acido N, N, N′,N′-tetraacetico, beta-mercaptoetanolo, glutatione, acido tioglicolico e 8-idrossichinolina.

Avvertenza

As supplied, this product is stable for one year at -20°C. There is no loss in FALGPA or protease activity in 30 days at 37°C, 50°C and -20°C. Solutions of crude collagenase are stable if frozen quickly in aliquots (at 10 mg/mL) and kept frozen at -20°C. Further freeze-thaw cycles will damage the solution. The product retains 100% activity over 7 hours when held on ice.

Definizione di unità

Una unità di digestione del collagene (CDU) libera peptidi da collagene proveniente da tendine d′Achille bovino equivalente in colore ninidrina a 1,0 μmole di leucina in 5 ore a pH 7,4 a 37 °C in presenza di ioni calcio. Una unità di idrolisi FALGPA idrolizza 1,0 μmole di furilacriloil-Leu-Gly-Pro-Ala per minuto a 25 °C. Una unità di proteasi neutra idrolizza caseina e produce colore equivalente a 1,0 μmole di tirosina per 5 ore a pH 7,5 a 37 °C. Una unità di clostripaina idrolizza 1,0 μmole of BAEE per minuto a pH 7,6 a 25 °C in presenza di DTT.

Nota sulla preparazione

Solutions are typically prepared at 1-2 mg/mL in TESCA buffer (containing 50 mM TES, 0.36 mM Calcium chloride, pH 7.4 at 37°C.
