| 摘要 |
The present invention provides methods of purifying encapsidated virus, e.g., viral particles comprising viral nucleic acid, from compositions comprising encapsidated viral nucleic acid and viral particles that lack viral nucleic acid; methods for reducing the particle:genome ratio in a preparation of encapsidated viral nucleic acid; and methods for selectively inactivating viral particles that lack viral nucleic acid in a liquid composition comprising encapsidated viral nucleic acid and the viral particles that lack viral nucleic acid. The methods generally involve subjecting the composition to hydrostatic pressure such that the viral particles lacking viral nucleic acid are selectively inactivated.
