  • Publication number: 20190345434
    Abstract: The present disclosure provides compositions and methods for extracting viral particles of a recombinant adeno-associated virus (AAV) or an adenovirus (AdV) from a sample comprising cells enclosing the viral particles. The method can include lysing the cells with the addition of an alkaline lysis solution to the sample such that the sample comprises compound(s) buffering pH value about 9.0 to about 11.5 and about 0.1% to about 1% of a detergent precipitating host cell proteins by adding a salting solution to the sample such that the sample comprises about 0.5 M to about 2.0 M of a salt and has a pH of about 4.0 to about 7.0.
