CHO Cell Culture Medium is a complete animal origin-free (AOF) and serum-free, ready-to-use formulation containing a plant hydrolysate for maximum productivity. This medium is formulated to support cell growth and production of antibodies and recombinant proteins in suspension CHO cell cultures.
GM CSF Human Recombinant produced in CHO cells is a 14.6kDa globular protein consisting of 127 amino acids, having two Application: Cell Culture
Ce… 9 rows He isolated the ovaries and grew extracted cells, later to be shown of fibroblastic lineage, in culture. The CHO cells were born. Shortly after, Puck and his junior colleague Fa-Ten Kao, sub-cloned the hamster cells and generated the CHO-K1 cell line, which would become a standard of mammalian cell culture in the decades to come. The cells were cultured in CD-CHO medium (Invitrogen, Life Technologies) in batch culture. Four sequential experiments were performed to test the effects of impeller speed, pH, temperature, and Highlighting the success of this cell line, more than 50% of the biopharmaceuticals approved in the US and Europe between 2006 and 2010 were produced in CHO cells 7. Happy birthday CHO. In the age of cell culture, CHO was there from the beginning and is still going strong at 60.
CHO cells grow quickly and easily and cell doubling time is 14-17 hours. 1. Rinse cells with 0.25% Trypsin/0.53mM EDTA 2. Add 3 mL of Trypsin-EDTA to flask and watch for cell layer detachment under an inverted microscope. This should occur within 5-15 minutes. Do not agitate cells during this type as agitation encourages clustering. If cells are not detaching, place in incubator for 5 minutes to facilitate dispersal.
CHO cells are the most common mammalian cell line used for mass production of therapeutic proteins. They can produce recombinant protein on the scale of 3-10 grams per liter of culture. Products of CHO cells are suitable for human applications, as they allow post-translational modifications to recombinant proteins which can function in humans.
CHO cells can be maintained as a suspension or as adherent to a substrate. For suspension, maintain cells in culture by revolving cultures 1 Jun 2008 Removing serum and products of animal origin from cell-culture media during production of therapeutic proteins from Chinese hamster ovary 15 Nov 2012 CHO cell cultures that are utilized for the production and (2005) developed a biphasic culture of CHO cells which a decrease from 37ºC to 9 Dec 2011 Recent advances in cell culture technology for rCHO cells have achieved significant improvement in protein production leading to titer of more The cell line (CHO-S) was adapted to suspension culture. These cells display a high metabolic rate and grow serum-free to yield cell concentrations of up to 2x10 6 In a typical cell line development workflow, CHO cells are transfected with an IgG fits in cell culture hood, proprietary cell cartridge prevents sample carry-over 5 Jan 1999 Sodium butyrate was added to CHO cell culture medium at a concentration of 1 mM after incubation of cells with BacMam1 GFP. Cultures were Fed-batch culture is commonly employed to maximize cell and product concentrations in upstream mammalian cell culture processes. Typical standard platform A majority of these complex molecules are produced by genetically modified mammalian cells in large-scale cell cultures.

Rodent cells were used to create the first homogeneous cell lines and media formulations. Many events occurred to bring CHO cells to the forefront in biotechnology. 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.

these accumulating compounds may e cell growth, productivitydecreas [17, 18], and protein quality [19, 20]. As monitoring the metabolites and changing the related pathways has the potential to improve recombinant protein production in CHO cell culture, these 45 compounds are presented in a tabulated form (Table 1). The table contains the main

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. To avoid coming into lab on the weekend, cells can be split to a lower density of 0.3×10 6 cells/ml on Friday.
Such media must support high viable cell densities while also stimulating the synthesis and extracellular transport of biologic products. Chinese Hamster Ovary cells (CHO) have been around a long time, since the 1960s and as with most of the early-cultured cells they are derived from a rodent. Rodent cells were used to create the first homogeneous cell lines and media formulations. Many events occurred to bring CHO cells to the forefront in biotechnology.

Developments in the composition of cell culture media have also resulted in serum-free chemically-defined media suitable for CHO cells. Use of these media has opened the possibility for xeno-free CHO protein production, which, combined with low risks of viral contamination, improves the chance of regulatory approval 3 .
