Fusion Proteins Pose Manufacturability Challenges
“Frequently, routine cell-culture and purification steps will need to be modified to address the tendency to form aggregates more easily,” notes Kalo.
Some fusion proteins are also prone to proteo…

Modeling Bioreactor Performance
Challener
Bioreactor design, including the geometry of the tank and impeller and the locations of inlets, has a direct impact on the performance of cell-culture and fermentation processes. Modelin…

Comparing Protein A Resins for Monoclonal Antibody Purification
As a consequence, downstream processing must accept and handle higher titers of mAbs in harvested cell-culture fluid (HCCF), and vendors of mAb purification technologies must develop chromatography re…

Cell-free Expression Systems Pose Cell Culture Alternative
Traditional cell-culture based biomanufacturing is a mature technology; however, it is tied to a living cell, which necessitates a great deal of complexity. That complexity ranges from the creation of…

New Therapies Present Scaling Challenges
New Therapies Present Scaling Challenges
Manufacturing differences between traditional mAb therapies and newer biotherapeutics dictate whether processes should be scaled up, scaled out, or use an al…
