Abstract
The present invention concerns the product produced by inactivating extracellular or intracellular pathogenic virus in a biological composition without incurring substantial disruption or inactivation of cells and without significant loss of labile proteins or other valuable biological components also contained therein, the inactivation process comprising subjecting said composition to a virucidally effective amount of irradiation in the presence of (a) a mixture of a compound that quenches type I photodynamic reactions and a compound that quenches type II photodynamic reactions or (b) a bifunctional compound that is capable of quenching both type I and type II reactions, to thereby inactivate said virus while retaining functionality of said composition. The composition is advantageously subjected to the irradiation and the mixture of compounds or bifunctional compound in the presence of an irradiation sensitizer. Moreover, the process can be advantageously combined with a different virucidal method to enhance virus inactivation.
