Examinator: Lars-Göran Mårtensson CHO Cell Culture CHO cells can be maintained as a suspension or as adherent to a substrate. For suspension, maintain cells in culture by revolving cultures continuously at approximately 50 RPM. Cell lines should be kept in such 10 mL “roller cultures”. 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.

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. 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. Multiple mammalian host cell lines have been used to manufacture therapeutic proteins, including CHO, NS0, BHK, HEK-293 and PER-C6.

Many events occurred to bring CHO cells to the forefront in biotechnology.

The table contains the main Figure 2: EX-CELL® 302 CHO-K1 Multiple Passage Spinner cultures were initiated from stationary cell cultures that were grown in EX-CELL 301 medium. Cultures were passaged every 4 - 5 days using a seeding density of 2 x 105 cells/mL. Cultures were monitored daily for maximum cell density after passaging.

However, the mechanisms controlling this metabolic shift are not yet fully understood. cells/mL) and a two-fold in trastuzumab titer (122 mg/L) in suspension batch culture. KEYWORDS best-ﬁt Box-Behnken, CHO cell line, DoE, folded-over Plackett-Burman, medium optimization, trastuzumab 1 INTRODUCTION Today, the most extended practice in the culture of mam-malian cells is the use of commercially available chemically CHO cells’ rapid rise in production prominence is due to their adaptability to various culture conditions, gene plasticity, and ability in proper folding, posttranslational modifications, and glycosylation of desired proteins.

Cultures were terminated when culture CHO cells are well established in the industry as they are well characterized with hundreds of CHO expressed molecules in the clinic. In fact, CHO cells have emerged as the gold standard expression system in biotherapeutics production, including mAb and non-mAb. diploid.

iii ABSTRACT pH is a key parameter in the optimization of animal cell processes, and has be linked to 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. Se hela listan på nanocellect.com CHO Cell Lines The CHO cell line is originally derived from the Chinese hamster ovary, and has become a staple source of cells due to their robust growth as adherent cells or in suspension. They are amenable to genetic modifications and methods for cell transfection, recombinant protein expression, and clone selection are well characterized. 1991-01-01 · In a recent paper, using CHO cells expressing the mouse c-myc gene, we showed that continuous application of high concentations of MTX during cell culture is associated with re-arrangement and variable amplification of transfected sequences in about 30-40% of cells (9). Using cells of the CHO-S, the combination of our CELLiST ™ and five types from other companies were compared in fed-batch culture. The model cell was adapted to each basal medium for 3 passages before evaluation in a flask.

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 . 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. The culture of Chinese Hamster Ovary (CHO) cells for modern industrial applications, such as expression of recombinant proteins, requires media that support growth and production. Such media must support high viable cell densities while also stimulating the synthesis and extracellular transport of biologic products.
