Multiple mammalian host cell lines have been used to manufacture therapeutic proteins, including CHO, NS0, BHK, HEK-293 and PER-C6. 1 However, CHO is used as the predominant host in the biologics industry due to its well-characterized genomic background and its relatively fast growth and high protein production in suspension culture.
CHO Cells. CHO cells (Chinese Hamster Ovary cells) are a laboratory-cultured cell line derived from cells of the ovaries of Chinese hamsters.Chinese hamsters are a popular laboratory mammal, partially due to their small size and low chromosome number, which makes them a good model for tissue culture and radiation studies.
CHO cells should be cultured in Ham’s F12K (ATCC suggestion) or DMEM modified with 10% FBS. If cells are not doubling every 14-17 hours, supplement the medium with 1-2% FCS. Subculture Protocol for KEYNOTE SESSION – CULTIVATING CHO CELLS. KEYNOTE PRESENTATION: 10:45 CHO: Optimizing Cell Culture Technologies for Manufacture of Recombinant Proteins - Past, Present and Future. Florian M. Wurm, PhD, Professor Emeritus, Swiss Federal Institute of Technology Lausanne (EPFL), and Founder & CSO, ExcellGene SA in CHO cell culture. Therefore, it seems worthwhile to revisit the issue of cell death in CHO cell culture with the concept of autophagy in mind, in order to achieve a maximum production of foreign proteins by protecting cells from both types of PCD. Chinese hamster ovary (CHO) cells are the most widely used Monitoring CHO Cell culture processes CHO cells are the most common mammalian cell line used for mass production of therapeutic proteins. Aber Radio Frequency Impedance (RFI) probes are commonly used to both monitor and control these processes. Example Cell Splitting Schedule. We recommend splitting suspension CHO cultures to a cell density of 2×10 6 cells/ml almost every day if the cells will be utilized for transient transfection experiments.

Using cells of the CHO-S strain, a comparison was performed of the costs when using our CELLiST ™ culture media and when using five types of fed-batch cultivation from other companies. When the total costs (Basal + Feed) and the cost per 1 g of antibodies (Total cost of each culture medium ÷ Titer for each on final day) are examined, our culture media can suppress the costs more than the The CHO-K1 cell line was derived as a subclone from the parental CHO cell line initiated from a biopsy of an ovary of an adult Chinese hamster by T. T. Puck in 1957. The cells require proline in the medium for growth. The base medium for this cell line is ATCC-formulated F-12K Medium, Catalog No. 30-2004.

Twenty dishes of confluent CHO 15B cells (4–6 × 10 7 cells per dish) were infected with 5–10 pfu (plaque-forming units) of VSV per cell. The cells were allowed to grow for 4 h in the presence of the virus. 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). A simple and efficient technique for CHO-cell cultures is presented that allows keeping the viable cell count X(v) and the specific growth rate μ of the cells on predefined trajectories. 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.
