Abstract
Biological compositions are freed of functional polynucletides by treatment of the biological composition with psoralen derivatives under irradiation conditions in which the proteins retain their original physiological activities and any polynucleotide present is rendered inactive. More specifically blood components are decontaminated of viruses by the addition of psoralen and irradiation and thereafter adding glucose.
