Aplicação
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 effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes. It is also suitable for the preparation adipocytes from epididymal fat pads of rats.
Ações bioquímicas/fisiológicas
Effective release of cells from tissue requires the action of both 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 (pH optimum: 6.3-8.8). The enzyme recognizes the sequence -R-Pro-8-X-Gly-Pro-R-, where X is most often a neutral amino acid.
A colagenase é ativada por quatro gramas de átomos de cálcio por mol de enzima. Ela é inibida por ácido etileno glicol-bis(beta-aminoetil éter)-N, N, N′,N′-tetracético, beta-mercaptoetanol, glutationa, ácido tioglicólico e 8-hidroxiquinolina.
Atenção
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.
Definição da unidade
Uma unidade de digestão de colágeno (CDU) libera peptídeos de colágeno do tendão de Aquiles bovino que equivalem em cor de ninidrina a 1,0 μmol de leucina em 5 horas em pH 7,4 a 37 °C na presença de íons de cálcio. Uma unidade de hidrólise de FALGPA hidrolisa 1,0 μmol de furilacriloil-Leu-Gli-Pro-Ala por min a 25 °C. Uma unidade de protease neutra hidrolisa caseína para produzir cor equivalente a 1,0 μmol de tirosina por 5 h em pH 7,5 a 37 °C. Uma unidade de clostripaína hidrolisa 1,0 μmol de BAEE por min em pH 7,6 a 25 °C na presença de DTT.
Nota de preparo
This product is prepared from Type II (C6885) Collagenase from Clostridium histolyticum. 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. It also contains clostripain, nonspecific neutral protease, and tryptic activities.

Protocolos
To measure collagenase activity, N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala is used in a continuous spectrophotometric rate determination at 345 nm. Collagenase hydrolyzes collagen peptide bonds.
