Ionic binding of biologically active proteins on cross-linked acrylic macromolecular supports.
The immobilization process of some biologically active proteins on acrylic ion exchange supports was studied. The cross-linking and swelling coefficient, as well as the molecular weight of the enzyme, were proved to influence the immobilization process. The kinetic data indicate mainly a binding process controlled by diffusion. The uptake coefficient values of different proteins ranged between 35.0 and 98.0%. The laboratory experiments per formed with some of the obtained enzymic preparation certify the preservation of the catalytic activity following the immobilization process.
