PROCESS FOR DEPLETING VIRUSES IN SOLUTIONS AND FOR DETERMINING THE DEPLETION RATE OF THE VIRUSES

摘要

In order to remove viruses from organic material, the material to be purified is passed through a filter or a filtration unit, the removal rate of which has previously been determined, in such a way that the filtration unit is inoculated with viruses of the leviviridae family. The virus titer is determined before and after filtration which establishes the removal rate. By following up on the removal of a marker substance the virus removal can be controlled in the ongoing process.
