Abstract:
Described herein are processes for purifying infectious virus particles and uses of protamine in such processes.

Claim (Index 3):
A process of purification of infectious virus particles, comprising the steps of:\n a) providing a crude harvest (a) comprising virus particles and impurities, wherein the impurities are generated from growing said virus particles on a cell substrate; b) reducing impurities from said crude harvest (a) by precipitation with an agent comprising protamine, preferably a protamine salt, more preferably a protamine sulphate, even more preferably a recombinant protamine sulphate, to obtain a virus preparation (b), wherein the enrichment of infectious virus particles in the virus preparation (b) relative to total virus products in the crude harvest (a) is in the range of at least 50% to 95%, preferably at least 80%.
