A process for purifying proteins especially enzymes which are directed to substrates which contain aromatic groups, in an aqueous medium, by adsorption, the proteins being fixed to a specific carrier material by hydrophobic adsorption, this carrier material containing phenylbutylamine groups covalently bound to the carrier material is described. Penicillinamidase may be immobilised by adsorption on the carrier, followed by treatment with a cross-linking agent. |
