Maximum Output Starts with Optimized Upstream Processing
The use of perfusion processes has enabled even larger throughputs within the same bioreactor volume.
Furthermore, Chilima observes that by using scalable technologies that have representative sca…

Hybrid Bioprocessing: A Q&A with Andrew Sinclair
In the upstream arena, people often refer to perfusion as a variant of continuous. This is a mature technology and the economics are well understood. Where the productivity of the cell line is equival…

Single-Use Technologies Prove Effective for Viral Vector Process Development
Finally, Ram points out that the use of perfusion in fixed-bed bioreactors is simpler than in traditional stirred tanks because the attachment matrix essentially acts as the cell retention device, whi…

Scaling Up Novel Therapies
One way they do this, he says, is by “scaling out,” intensifying processes, for example by using fed-batch and perfusion on the upstream side, and multicolumn operations, whether it’s just higher cycl…
