A Next Generation Protein A Chromatography Resin for Improved Productivity and Bioburden Control
• The increased upstream titers in mAb production seen in recent years may make the Protein A capture step a bottleneck.
• Protein A columns columns are also more prone to bioburden contamination…

Cost Considerations Drive Lean Technology in Biopharmaceutical Manufacturing
By Catherine Shaffer
Four biosimilars have been approved for the market by FDA as of February 2017, and more are in the pipeline. Now that biosimilars are here to stay, manufacturers are devel…

Validation of Cytodex™ Gamma microcarrier-based virus production in single-use bioreactor systems
A majority of cell lines commonly used for viral vaccine production are anchorage-dependent and require expansion on solid surfaces. Here, we describe different approaches for the cultivation of Ver…

Process Chromatography Selection for Downstream Processing Applications
Improvements in upstream processing have increased titers, shifting bottlenecks downstream from being a volumetric issue to where it is mainly the binding capacity of the resin that is limiting.

Perfusion in the 21st Century
Dramatic increases in the titers achievable with fed-batch culture, which reached levels as high as 4.7g/L (3), eventually eliminated the need to pursue continuous processing for increased productivit…
