Description

Descrição geral

Collagenase from Clostridium histolyticum comprises of collagenases G and H. Collagenase has N-terminal activator domain and C-terminal peptidase domain. The collagen binding domains (CBD) and polycystic kidney disease-like (PKD-like) domain resides in the peptidase domain. The collagenase module undergoes structural changes upon calcium binding.

Aplicação

Collagenase from Clostridium histolyticum has been used:

• for the recovery of neutrophils from collagen gels
• for the dissociation of breast tumor biopsies into single cells
• for the isolation of primary human endometrial stromal cells(HESC) from endometrial biopsies

Collagenase from Clostridium histolyticum may be used for the isolation of cells from many types of animal tissue. It may be used for the disaggregation of human tumor, mouse kidney, human adult/fetal brain, lung and many other tissues. It may also be used in liver and kidney perfusion studies, for the digestion of pancreas, isolation of nonparenchymal rat liver cells and for hepatocyte preparation.

Ações bioquímicas/fisiológicas

Crude collagenases are mixtures of enzymes (mostly proteases) secreted by C. histolyticum. 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.

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.

Embalagem

Product sold on the basis of collagen digestion units (CDU).

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

Collagenase may be dissolved in TESCA buffer (50 mM TES, 0.36 mM Calcium chloride, pH 7.4 at 37 °C) at 0.05-0.1 mg/mL concentration.
