The formulation of the culture medium for a Chinese hamster ovary (CHO) cell line has been investigated in terms of the simultaneous replacement of glucose and glutamine, the most commonly employed carbon and nitrogen sources, pursuing the objective of achieving a more efficient use of these compounds, simultaneously avoiding the accumulation of lactate and ammonium in the medium. Chinese hamster ovary (CHO) cells are used to evaluate chromosomal aberrations.

Development of a culture system for modeling of pH effects in CHO cells, Master’s Thesis, 2011. 1 1 INTRODUCTION Chinese Hamster Ovary (CHO) cells are widely used within biotechnological research and industry, in particular for the recombinant production of biopharmaceuticals. The

Introduction to CHO Culture in a Stirred-Tank Bioreactor Richard Mirro, Eppendorf Inc., Enfield, CT, USA Contact: becken.u@eppendorf.com Introduction Chinese Hamster Ovary cells, or CHO cells, are commonly used in biotechnology for protein production in the growing Puck’s extreme enthusiasm for the cultivation of CHO cells shows that the original hamster must have been a very unusual animal: “Cultured Chinese hamster lung, kidney, spleen and ovary cells divided rapidly; it was possible to keep the ovary cells in culture for more than ten months with no decrease in the cell division rate and no morphological changes.” (J. Exp. Med. 108, 945 ff., 1958). The CHO cells were first used in laboratory work in 1919 but the culture technique was established in 1957, when Dr. Theodore T. Puck identified conditions for good viability and fast growth. After that, CHO cells began to be intensively used as host cells. They grow fast with good viability and are easy to culture. The post-translational CHO-S cell line (ThermoFisher Scientiﬁc, Waltham, MA, USA). Also, a serum-free suspension-adapted CHO-S cell line expressing trastuzumab (Cobra Biologics AB, Keele, UK) was tested with the optimal condition obtained in this study.
