Aplicación

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.

Acciones bioquímicas o 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.
La colagenasa es activada por cuatro átomo-gramos de calcio por mol de enzima. Es inhibida por el ácido etilenglicol-bis(beta-aminoetil éter) - N, N, N′,N′-tetraacético, el beta-mercaptoetanol, el glutatión, el ácido tioglicólico y la 8-hidroxiquinolina.

Precaución

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.

Definición de unidad

Una unidad de digestión de colágeno (CDU) libera péptidos del colágeno del tendón de Aquiles bovino que equivalen en la reacción de color de la ninhidrina a 1,0 μmoles de leucina en 5 horas a pH 7,4 y 37 °C en presencia de iones calcio. Una unidad de hidrólisis FALGPA hidroliza 1,0 μmoles de furilacriloil-Leu-Gly-Pro-Ala por minuto a 25°C. Una unidad de proteasa neutra hidroliza la caseína para producir color equivalente a 1,0 μmoles de tirosina por 5 horas a pH 7,5 y 37°C. Una unidad de clostripaína hidroliza 1,0 μmoles de BAEE por minuto a pH 7,6 y 25°C en presencia de DTT.

Nota de preparación

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.

It has been widely postulated that scaffold permeability has a significant influence on chondrogenesis. However, since permeability has not been rigorously controlled in previous studies, there is no definitive conclusion as to how permeability affects cartilage regeneration by primary chondrocytes
