Impact of Media Components on CQAs of Monoclonal Antibodies
Non-animal derived hydrolysates from soy, wheat, and yeast are commonly used in cell culture media.
Protective agents and detergents
These chemicals are typically used to reduce the shear stres…

Process Chromatography: Continuous Optimization
Even so, there are many impurities present in the harvest cell-culture fluid obtained after removal of the cells or yeast and media. Host-cell proteins, host-cell DNA, other process-related contaminan…

The New World of Biopharmaceutical Manufacturing
The number of drugs that are produced by non-mammalian expression systems, such as yeast and microbes, will continue to climb; these will require more highly engineered microbial bioreactors.

Ensuring the Biological Integrity of Raw Materials
Those include bacteria, yeast, molds, viruses, and sometimes prions.
Mycoplasmas are the smallest of free-living organisms, and are frequent contaminants of mammalian cell cultures. They can alter…

Safety Drives Innovation in Animal-Component-Free Cell-Culture Media Technology
The earliest examples of successfully eliminating animal-sourced materials relied heavily on substituting complex, undefined alternatives such as vegetable protein hydrolysates or yeast extracts. Thes…

Implications of Cell Culture Conditions on Protein Glycosylation
Rapid production of proteins with primitive glycosylation can be achieved using yeast. Insect cells, generally used with a baculovirus vector in transient fashion, are used mostly for R&D and niche pr…

Advanced Technologies Facilitate Scale-up and Technology Transfer
The situation is different for microbial cultures based on Escherichia coli and yeast, for example. These processes have high growth rates and densities, and thus the demand for oxygen is high, making…
