Combining Microbioreactors and Advanced Statistical Techniques to Optimize a Platform Process for a New Host-Cell Line
First, the availability of high-throughput miniature bioreactors has made it possible to evaluate many more conditions. This has enabled design of experiment (DoE) approaches, such as response surface…

Best Practices in Qualification of Single-Use Systems
Aseptic connector devices, mixer bags, storage bags, and bioreactors followed. Currently, single-use systems (SUS) also include disconnectors, disposable filling needles, and sensors. The technology i…

Evaluating the Use of Continuous Chromatography
…h is a useful approach when the purification step is connected to an upstream perfusion or fed-batch bioreactor, and, by having two or more columns in the loading zone, you can overload the first col…

Best Practices for Selecting a Top-Quality Cell Line
Before scaling up to bioreactors, the productivity level for monoclonal antibodies (mAbs) should be 2–7 g/L (fed-batch culture in shake flask) or greater, observes Selexis CEO Igor Fisch. Once scaled …

Ensuring Viral Safety of Viral Vaccines and Vectors
Extraneous vesiviruses, however, have recently appeared in bioreactors (2–5), and porcine circovirus type 1 (PCV-1) contamination of oral rotavirus vaccines was first reported by a metagenomics analys…

Optimizing Late-Stage and Commercial Cell-Culture Processes
This resulted from the introduction of parental cell lines better suited to modern fed-batch processes and the development of better bioreactor processes, including control strategies for pH, carbon d…

Challenges in Cell Harvesting Prompt Enhancements
Biomanufacturers have been shifting from large stainless-steel bioreactors in the thousands-of-liters range to smaller, disposable bioreactors (2).
The need to address this bottlenecking issue …

Designing a Biomanufacturing Facility Incorporating Single-Use Technologies
For example, one can consider 2 x 2000-L bioreactors running a typical 14-day incubation period staggered a week apart, which equates to one batch produced each week. A typical batch at 2 g/L with a 7…

A Risk-Based Genetic Characterization Strategy for Recombinant CHO Cell Lines Used for Clinical and Commercial Applications
Generation 0 (G0) represents the generation of a master cell bank, G30 represents the generation of cells harvested from a 5000-L bioreactor, and G60 represents the limit for in vitro cell age designe…
