How to Improve Protein Productivity Through Scale Up, Including Single-Use Bioreactors
Enhancing protein production is a common goal in the biomanufacturing industry. However, scalability is a problem faced across many platforms in manufacturing. A desired outcome observed in shake flasks, such as increased protein productivity, is not always observed in large scale bioreactors. Further, the move toward single-use bioreactors has posed an additional challenge, as productivity improvements observed in glass shake flasks or stainless steel bioreactors may not be observed in plastic bioreactor bags. Availability of lipids in media is one factor to consider during bioproduction scale-up and when moving toward single-use system.
During this Ask the Expert session, we will be discussing considerations to be made regarding bioproduction scale-up and single-use bioreactors. Essential Pharmaceuticals is addressing these challenges with their Cell-Ess lipid supplement. Cell-Ess was used as a feed at 5% (v/v) in a small Wave bioreactor resulting in greater than 25% monoclonal antibody titer increase, which was similar to the gains seen in earlier experiments using shake flasks. Small bioreactors have been used as models to show scalability to up to 10,000-liter manufacturing runs. These new data suggest supplementing with Cell-Ess as a feed will result in increased monoclonal antibody titers for 10,000-liter bioreactor runs, including in single-use bioreactors.
