2014-08-23 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 sector of mammalian cell culture. Mammalian cell culture L-glutamine, EX-CELL 302 will support growth of CHO-K1 cells in batch suspension cultures for greater than eight (8) days while maintaining high cell viability (> 70%). This long culture period and stationary phase allow for an extended production period and higher culture productivity. Additionally CHO cells so not express the EGR receptor so the cell line was used in reconstitution studies to demonstrate the structure/function of the receptor. As time went on, CHO cells were selected for recombinant protein production because they grew well in culture and some of the CHO lines had selection capabilities for cells containing recombinant DNA plasmids.

S.N.Z AND ANUAR. N Department of Chemical and Process Engineering, Faculty of Engineering, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor. zakiah.zainul@yahoo.com Bacterial and mammalian cell suspension cultures are used in many ways e.g. in biotechnology for the production of compounds, and as model systems in fundamental research. Especially in medical research liquid cultures remain essential to facilitate the understanding and treatment of diseases.

Cell Culture Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis. 15 Oct 2020 Adapting cell lines to serum-free suspension culture is just one of the Expand the cultures like CHO K1 or HEK293 in currently used medium. I assume you are transitioning in a serum containing media like Ham's F12 for your CHO cells, since serum-free media is generally made for suspension culture . The last step of developing the technology and adapting CHO cells to large-scale suspension cell culture in bioreactors was far from trivial, but lead the Moreover, CHO cells growing in suspension culture with Sigma C5467 medium can be directly transferred to T-flasks or roller bottles with C8730 medium for a Expression Systems offers 293 and CHO mammalian cell lines adapted to serum -free suspension culture in ESF SFM.

Here, we illustrate the increasing heterogeneity in the cellular transcriptome of serum‐free adapted CHO K1 cells during high cell density suspension culture over time without concomitant changes in the genomic sequence. A method of producing biologically active human tissue plasminogen activator in suspension culture is provided wherein recombinant Chinese hamster ovary cells are cultured and certain components detrimental to recovery and biological activity are removed as a cell-free filtrate by cross-flow filtration. The human tissue plasminogen activator is recovered from the culture medium.
