VERFAHREN ZUR ABREICHERUNG VON VIREN IN LOESUNGEN UND ZUR BESTIMMUNG DER ABREICHERUNGSRATE VON VIREN

摘要

To deplete viruses in organic material, the material to be purified is conveyed through an ultrafilter or an ultrafiltration unit the depletion rate of which is previously determined. The filter or filtration unit is charged with viruses of the family Leviviridae and the viral count is determined before and after filtration and used to derive the depletion rate. The virus depletion can be monitored during the process by following the depletion of a marker.
