Transient transfection at large scale for clinical AAV9 vector manufacturing

 

‌AAV9 production in adherent HEK293 cells was scaled from the pilot iCELLis® Nano bioreactor to the large scale iCELLis 500 bioreactor (200 m2 and 333 m2 surface area). A HEK293 cell seed train was utilized, using the Xpansion® 200 bioreactor. Media components were evaluated and replenished as needed throughout the run using the perfusion process of the iCELLis bioreactor. Following a production phase, >1016 vector genomes were isolated from crude harvest of the bioreactor.
