About PackGene Biotech INC

PackGene is a world-leading adeno-associated virus (AAV) vector CRO and CDMO company. We provide economical, reliable, and scalable plasmid DNA and AAV viral vector production for early-stage drug discovery, preclinical development and clinical trials for Cell and Gene Therapy (CGT). Our proprietary π-Alpha 293 AAV High-yield Platform uses uniquely designed RC plasmid in the triple-plasmid transfection system to increase AAV production by 3 to 8 fold. By combining in-process upstream and downstream QbD optimizations we further increase total AAV yield up to 10 fold. A single batch of AAV production at PackGene delivers up to 1E+17vg virus particles – enough to meet most commercial and clinical project requirements.
