Abstract
Biological compositions are decontaminated by treatment with furocoumarin derivatives and irradiation under particular conditions in which the proteins retain their original physiological activities and any pathogenic microorganisms and polynucleotide fragments thereof are rendered inactive. It has been found that reduction of the amount of dissolved oxygen in the treatment solution substantially inhibits denaturation of the proteins.
