High Cell Density Cultivation of HEK293 Cells Using a 2L Membrane‐Stirred Bioreactor
Biotechnology and Bioengineering, EarlyView.ABSTRACT The use of perfusion systems for the continuous cultivation of animal cells at high cell density (HCD) for the production of recombinant proteins, viruses, and viral vectors has many advantages. Besides an enhancement of volumetric productivity and high cell viability, the product quality can be improved through a steady‐state environment ...

Jet injection studies for partially baffled mixing reactors: a general correlation for the jet trajectory and jet penetration depth [PDF]
, 2008 This paper is devoted to the analysis of the jet trajectories, obtained using computational fluid dynamics (CFD), at two different scales (laboratory and industrial) with application to quenching of runaway reactions. One of the goals was to describe how

Biotechnology and Bioengineering, EarlyView.ABSTRACT Maintaining consistent cellular physiology during bioprocess scale‐up or scale‐down is key to developing robust processes. However, the reliability of scale‐down bioreactor systems remains debated. Although the calibration of physiological parameters in mechanistic models across scales has been proposed as a scale‐down strategy, few studies ...

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up
Biotechnology and Bioengineering, EarlyView.ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.
