Method of immobilizing enzymatically active materials |
摘要 |
This invention discloses a method of immobilizing an enzymatically active material to a water-insoluble polyanion which comprises bringing a polycation-containing aqueous medium and the enzymatically active substance into contact with the water-insoluble polyanion having any desired form. This method is characterized in that the enzymatically active substance is adsorbed on the surfaces of the water-insoluble polyanion and, at the same time, a strong complex is formed by the interaction of the polycation and the polyanion to produce a water-insoluble film. As a result, the enzymatically active substance so adsorbed is securely fixed to the surfaces of the water-insoluble polyanion and scarcely released therefrom.
