435/173.3, Modification of viruses (e.g., attenuation, etc.)435/2, MAINTAINING BLOOD OR SPERM IN A PHYSIOLOGICALLY ACTIVE STATE OR COMPOSITIONS THEREOF OR THEREFOR OR METHODS OF IN VITRO BLOOD CELL SEPARATION OR TREATMENT435/173.1TREATMENT OF MICRO-ORGANISMS OR ENZYMES WITH ELECTRICAL OR WAVE ENERGY (E.G., MAGNETISM, SONIC WAVES, ETC.)
Viral and bacterial contaminants present in biological solutions are inactivated by mixing one of a novel class of photosensitizer with said solution and irradiating the mixture. Quinoline and quinolone compounds are useful as photosensitizers in this method. With certain photosensitizers a blocking agent may also be employed.
