Abstract
Here we describe the development of a two-step chromatography process based on the use of ion-exchange resins for the purification of recombinant adeno-associated virus (rAAV) serotypes-2 and-5. In vitro and in vivo results demonstrate that this method, which does not require any prepurification step of the cell lysate, can be applied to obtain highly pure rAAV2 and rAAV5 stocks. As such,this procedure can be easily transferred in vector cores and also scaled up, allowing the direct comparison of these two, and potentially other, AAV serotypes in large animal models.
