Antibody Production in Microbial Hosts
Challenges associated with the production of antibodies in microbial hosts
Microbial cells such as yeast and bacteria possess many advantages, such as fast growth, well-known genetics, and low…

Addressing the Challenges in Downstream Processing Today and Tomorrow
In addition to high cell density mammalian expression, expanded utilization of other expression systems such as microbial and yeast will support these newer biotherapeutics (BioTx). The diversity of B…

Paring Down Impurities in Downstream Processing
Biopharmaceutical expression systems range from yeast and insects to mammals and plants. Bioreactors to house these systems might be stirred-tank, air-lift, fixed-bed, hollow-fiber perfusion, or suspe…

Recent Advances in the Use of Exoglycosidases to Improve Structural Profiling of N-glycans from Biologic Drugs
First, recombinant production of all enzymes was achieved in Escherichia coli or yeast hosts. This required discovery of some genes encoding plant enzymes that had never been produced recombinantly (e…
