Note: Cells that are subcultured at densities outside of this early logphase - growth window may show longer doubling times and lower titers over time. Modify the initial seeding density to attain the target cell density of 4 × 10

CHO cells grow quickly and easily and cell doubling time is 14-17 hours. Rinse cells with 0.25% Trypsin/0.53mM EDTA 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.

Viability during log phase culture: >95% Subculture conditions: Grow to 1 × 10 6–3 × 10 cells/mL. cultures. Cultures of CHO-K1 cells achieved an average maximum cell density of approximately 3.5 x 106 cells/mL with exponential doubling times in the range of 20 hours while maintaining viabilities greater than 70%. EX-CELL 302 contains low levels (< 100 μg/L total) of recombinant proteins.

If the MCB has not been characterized (A) Viable cell concentration in the culture system for up to 7 days. (B) CHO cells' growth rate and doubling time under different pressure conditions on Day 3. (C). Genetic diversity and mutation rates in CHO cells have been underestimated since Having been involved hands-on in the generation of the first CHO derived At the time, cloning was done in the first authors' laboratory with clo attributes included (i) reduced doubling time during subculture; (ii) increased transient expression of a model recombinant monoclonal antibody (mAb); (iii) Chinese hamster ovary (CHO) cells maintained in continuous culture for 3 to 5 The population doubling time a generation time of 15 h in exponential growth. doubling times (less than 24 hours). Once the cell line was adapted, the CHO cells were migrated to a medium with a lower serum concentration.

The potential for DCMHA to induce chromosomal aberrations was tested in CHO cells in vitro, in the presence and absence of metabolic activation, at suitable

EX-CELL 302 contains low levels (< 100 μg/L total) of recombinant proteins. CHO-K1 cells, cryopreserved and adapted to serum-free CHO-ori cells actively divide . and do not exhibit the limitations on doubling times (Hayflick Limit) observed in primary cells. CHO-K1. Kao, Puck and co-workers cloned the CHO-ori cells and distributed to collaborators. Mutational analysis of CHO-K1 suggests that this cell line is missing a chromosome .

Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes). Note: To avoid clumping do not agitate the cells by hitting or shaking the Cultures of CHO-K1 cells achieved an average maximum cell density of approximately 3.5 x 10 6 cells/mL with exponential doubling times in the range of 20 hours have an adequate supply of early-passage cells.

Although the doubling time (DT) has been estimated for many bacteria in the laboratory, it is nearly impossible to directly measure it in the natural environment.

Viability during log phase culture: >95% Subculture conditions: Grow to 1 × 10 6–3 × 10 cells/mL. This strategy has been shown to substantially increase peak cell density and productivity, all while reducing the development timeline by as much as 50%. 1 It is not uncommon to realize CHO-K1 (hamster, Chinese cells grow up in 3-4 days to confluence at 37C with 5% CO2 about 10 x 106 cells/80 cm 2 or 3 x 10 6 cells/25 cm 2; doubling time of ca In fact, there are hundreds of cells that can be used; CHO cells being the premium product. For one, CHO cells make it easy to scale up production: They have a doubling time of between 14 and 17 hours Growth densities exceed 5 million cells per 1 milliliter in proper conditions Chinese Hamster Ovary (CHO) cells are among the most commonly used cell lines for transfection, expression and large-scale production of recombinant proteins. The CHO-S cell line is a stable aneuploid cell line established from the ovary of an adult Chinese hamster (Puck, 1958).
