Purification of Recombinant Adeno-Associated Viruses (rAAVs) by Iodixanol Gradient Centrifugation

Cold Spring Harb Protoc. 2020 Feb 3;2020(2):095612. doi: 10.1101/pdb.prot095612.

Abstract

This is a simple method for rapid preparation of recombinant adeno-associated virus (rAAV) stocks, which can be used for in vivo gene delivery. The purity of these vectors is considerably lower than that obtained by either CsCl gradient centrifugation or by combination of iodixanol gradient ultracentrifugation followed by column chromatography.
