A METHOD FOR DEPLETING VIRAL AND MOLECULAR PATHOGENS IN A BIOLOGICAL MATERIAL

摘要

A process is disclosed for reducing the concentration of viral and molecular pathogens in a biological material which contains one or several biological substances to be extracted. The biological material is mixed with an organic solvent, the biological material mixed with the solvent is brought into contact with an ion exchanger, pathogens are adsorbed by the ion exchange material and at least one of the biological substances to be extracted interacts to a reduced extent or not at all with the ion exchanger, then the ion exchanger with the adsorbed pathogens is separated from the biological material. A preparation of the biological substance with a reduced virus concentration is thus obtained.
