ABSTRACT:
Biologically active substances such as enzymes are immobilized in the pores of a porous support material by introducing a solution of the biologically active substance into the pores of the support material, treating the active substance in the pores to temporarily retain the active substance in the pores and immobilizing the active substance in the pores by crosslinking. Temporary retention of the active substance in the pores may be carried out by precipitation with a precipitating agent or by freeze-drying.
