Isolation of AAV particles from AAV particle-producing cells is conventionally performed using the freeze-thaw or sonication methods. However, these methods are time consuming and require special equipment. The AAVpro Extraction Solution is a reagent for the extraction of AAV particles from AAV particle-producing cells. This reagent provides a simple and efficient method for AAV particle isolation; the reagents are added to virus-producing cells and viral particles are recovered by centrifugation. The extracted AAV particle solution contains only a small amount of host protein and nucleic acid contamination. The resulting viral extract is well-suited for cell infection or further purification of viral particles.

The purity and titer of the AAV vector is an important for achieving stable and effective introduction of genes into individual animals and cultured cells. Methods such as CsCl concentration gradient ultracentrifugation and iodixanol ultracentrifugation are commonly used to purify AAV2 vectors, but such methods are time-consuming and require careful technique to obtain high yields. The AAVpro Purification Kit (AAV2) allows for simple and fast (~4 hours) AAV2 particle purification from AAV2-producing cells.
