  • Method using filtration aids for the separation of virus vectors from nucleic acids and other cellular contaminants
    Publication number: 20010043916
    Abstract: Methods are disclosed for the purification of encapsulated viruses. The methods are advantageous in that they employ filtration aids, together with low concentrations of metal ions, in place of nucleases for purification. This provides important advantages for commercial scale purification of viruses.
