Transformation of free radicals of gamma-irradiated enzymes during long-term storage

The ESR method was used to study free radical processes occurring in gamma-irradiated enzymes upon their long-term storage (up to 4 years) both at room temperature and at 4 degrees C. Simultaneously, studied was the biological activity of gamma-irradiated enzymes subjected to a long-term storage. Th...

Summary:The ESR method was used to study free radical processes occurring in gamma-irradiated enzymes upon their long-term storage (up to 4 years) both at room temperature and at 4 degrees C. Simultaneously, studied was the biological activity of gamma-irradiated enzymes subjected to a long-term storage. The immobilization of enzymes on dialdehyde cellulose or polycaproamine was shown to preserve their biological activity during the postirradiation storage.
