April 05, 2012 • Written by Brandy Sargent . In a previous blog “Strategies for Improving Antibody Production in CHO Cells” three areas were identified where antibody production can be improved. In part one of the series titled “Utilizing Gene Synthesis to Improve Antibody Production in CHO Cells,” we looked proteins into the cell culture supernatant, which facilitates downstream processing. Since the first use of CHO cells for recombinant protein expression, production processes have steadily improved Transient antibody production is performed by expressing recombinant monoclonal antibodies in mammalian expression systems, mainly HEK293 cells and CHO cells.

The first approved therapeutic monoclonal antibody produced in a CHO cell line was Rituxan, an anti-CD20 antibody used for the treatment of non-Hodgkin’s lymphoma (Genentech, 1997). But since then, researchers have generated impressive amounts of data on CHO genetics, which recently culminated with the determination of the CHO genome in the early 2010s.
