Title (EN) IMMOBILIZED CHOLINESTERASE ENZYME PREPARATIONS AND A PROCESS FOR THE PREPARATION THEREOF
(FR) PREPARATIONS D'ENZYMES DE CHOLINESTERASE IMMOBILISES ET LEUR PROCEDE DE PREPARATION
Abstract:
(EN) Immobilized cholinesterase enzyme preparations are prepared by treating a polymeric resin, built up from acrylic acid and/or methacrylic acid and acrylamide and/or methacrylamide monomers with an acryl or allyl type cross-linking agent and contains at least 0.1 meq/g of -COOH funtional groups, with a carbodiimide derivative which is soluble in water or is soluble in an organic solvent at temperatures below 0oC, applying a solution of cholinesterase enzyme with a pH of 4.5 to 8.5 onto the resulting activated support, washing the resulting product, and drying it then, if desired.
(FR) Des préparations d'enzymes de cholinestérase immobilisés sont préparées en traitant une résine polymère, composée d'acide acrylique et/ou d'acide méthacrylique et de monomères d'acrylamide et/ou de méthacrylamide avec un agent réticulant du type acryl ou allyl et contenant au moins 0,1 meq/g de groupes fonctionnels -COOH, avec un dérivé de carbodihymide soluble dans l'eau ou soluble dans un solvant organique à des températures inférieures à 0oC, en appliquant une solution d'enzymes de cholinestérase avec un pH situé entre 4,5 et 8,5 sur le support activé résultant, en lavant le produit résultant et facultativement en le séchant.
