ABSTRACT:
The invention relates to a method for preparing viral suspensions. The invention relates in particular to a method for preparing high-titer viral suspensions in cell cultures. Preferred methods include increasing the volume of the cell culture prior to infection with viral material and subsequent further steps of expanding the volume to a final volume which is distinctly larger than the maximum culture volume prior to infection.
