Typical set-points for pH in CHO cell culture are in the range between 6.8 and 7.4. Throughout the culture, strategies to maintain the pH at the desired set point are required, since the pH is continuously influenced by the activity of the cells, i.e. the production of acidic by-products.

Chinese Hamster Ovary cells, or CHO cells, are commonly used in biotechnology for protein production in the growing sector of mammalian cell culture. Mammalian cell culture has become increasingly popular due to the ability of Eukaryotic cells to achieve more complex post-translational modification of proteins. APPLICATION NOTE No. 250 I October 2011

In this regard, media supplementation plays an important role in searching for best production conditions since product titer is proportionally related to the number of viable cells in almost all cases [6,8]. consistency. A Chinese Hamster Ovary cell line (CHO 320) producing human interferon-y (IFN-y), a glycosylated protein, was chosen to investigate the effects of the culture environment on (I) cell growth, (2) product yield and (3) product authenticity. A statistical approach was used to identify important culture components for cell growth and Cho cells 1.

Incubate cultures at 37°C. 2017-09-26 · In a previous study on the selection of basal media and feeds for CHO cell fed-batch cultures (Pan et al. 2017), it was observed that a cell size increase occurred after the exponential growth phase when ActiCHO feed A/B (GE Healthcare) was used but not when Efficient feed A, B, and C (Gibco™) were used. CHO TF SILAC Medium is a complete chemically defined, animal-component–free cell culture medium variant without arginine and lysine.Therefore it can be used for SILAC (stable isotope labeling by/with amino acids in cell culture) experiments.

If Accutase® is used, washing with serum-containing cell culture medium is not always required since it inactivates at 37 °C in about 45 Cells that are cultured in suspension can be maintained in culture flasks that are not tissue-culture treated, but as the culture volume to surface area is increased beyond which adequate gas exchange is hindered (usually 0.2 – 0.5 mL/cm 2), the medium requires agitation.

The CHO and CHO-K1 cell lines can be obtained from a number of biological resource centres such as the European Collection of Cell Cultures, which is part of the Health Protection Agency Culture Collections. These organizations also maintain data, such as growth curves, timelapse videos of growth, images, and subculture routine information.

Switch to a suspension system at this point. CHO cells were grown in tissue culture dishes.

Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels.

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.

We found that more than 80% of the cells in a standard serum-free batch culture of CHO cells in suspension died via apoptosis—as evidenced by condensed chromatin and the appearance of a characteristic DNA ladder.
