Viral vector N-1 intensification reduces seed train vessel number, media volume and time

Viral vector N-1 intensification reduces seed train vessel number, media volume and time

The demand for gene therapy viral vectors requires manufacturing processes to scale up to 2000 L. Viral vector production at this scale requires a 9- to 12-day seed train with two to three seeding bioreactors, increasing the risk of failure and manufacturing cost. Perfusion-based cell culture intensification techniques shorten and simplify the seed train for recombinant proteins and monoclonal antibodies production by reducing time, equipment, bioreactor size and cost while increasing the potential number of batches per year. This webinar will discuss similar efficiency gains for three different viral vectors (lentivirus, AAV8 and AAV9) through intensification using KrosFlo® TFDF® Technology that resulted in reduce train vessel number, N-1 vessel size, media volume and time.
