Abstract

Procédé de préparation de clostripaïne pure lyophilisée. Le milieu de culture de Clostridium histolyticum ou la collagénase brute obtenue à partir de Clostridium histolyticum est mise en solution dans un tampon compatible avec le maintien de l'activité enzymatique de la clostripaïne, après quoi cette solution est purifiée par chromatographie d'affinité à l'aide d'un inhibiteur spécifique de la clostripaïne, lié par liaison covalente à un support inerte insoluble et hydrophile, la clostripaïne retenue sur la colonne étant ensuite éluée par le même tampon associé soit à du dithiothreitol, soit à un gradient de chlorure de sodium, la clostripaïne pure obtenue étant ensuite lyophilisée. Application à l'obtention de la clostripaïne pure lyophilisée présentant une activité spécifique au moins égale à 1 mu kat/mg.
