Upstream Viral Vector Manufacturing: Transfections of Adherent Cultures at Scale

Presented by

Cassie-Marie Peigné, PhD, Polyplus-transfection® and Ann Rossi Bilodeau, PhD, Corning Life Sciences

About this talk

Many cell and gene therapy applications are dependent on viral vectors for recombinant gene delivery. Efficient transfection of a large biomass of cells represents a significant challenge for transient viral vector production systems. However, identifying a scalable adherent cell culture platform for high density cell culture and relying on a transfection reagent that can ensure robust and reproducible viral yields at scale are essential to streamline transition from process development to manufacturing. Introduction: 1:36 – 7:57 – Viral vector use in cell and gene therapy applications – Challenges for vector production Considerations for Choosing a Cell Culture Platform: 7:58 – 14:43 – Adherent versus suspension – Typical upstream scale-up/scale-out Bottlenecks to Scalable Transfections: 14:44 – 30:40 – Science behind Polyplus® reagents, featuring PEIpro® – Protocol review for Corning® CellSTACK® and CellCube® vessels Q&A Session: 30:41 – 43:09
