Abstract
PURPOSE: To produce titled composition firmly fixing a bioactive substance at low temperature within a short time, by adding glutaraldehyde to a mixture of a bioactive substance and a vinyl type polymerizable monomer, and irradiating the resulting mixture with an ionizing radiation.
CONSTITUTION: To an aqueous solution or buffer solution containing a bioactive substance such as human adult cornea or cellulase are added 1W10wt% at least one vinyl type polymerizable monomer such as ethylene glycol diacrylate and 1W10wt% glutaraldehyde, and the resulting mixture is irradiated with an ionizing radiation at 0W10°C and at a dosage of about 1×105 Roentgen to polymerize the monomer and to form a fixed product which is the entire system fixed to form a pudding-like material.
EFFECT: It is possible to keep the life for a ling time by cutting the fixed product into pieces of an appropriate size and storing the pieces in a buffer solution.
