{Abstract}: The insect cell-baculovirus expression vector (IC-BEV) platform has enabled small research-scale and large commercial-scale production of recombinant proteins and therapeutic biologics including recombinant adeno-associated virus (rAAV)-based gene delivery vectors. The wide use of this platform is comparable with other mammalian cell line-based platforms due to its simplicity, high-yield, comparable quality attributes, and robust bioprocessing features. In this chapter, we describe a rAAV production protocol employing one of the recent modifications of the One-Bac platform that consists of a stable transformed Sf9 cell line carrying AAV Rep2/Cap5 genes that are induced upon infection with a single recombinant baculovirus expression vector harboring the transgene of interest (rAAV genome). The overall protocol consists of essential steps including rBEV working stock preparation, rAAV production, and centrifugation-based clarification of cell culture lysate. The same protocol can also be applied for rAAV vector production using traditional Three-Bac, Two-Bac, and Mono-Bac platforms without requiring significant changes.
