Subcultivation of CHO cells in suspension culture using the commercial serum-free medium EX-CELL™302, which contained an IGF-1 analog, supplemented with LPA resulted in gradually increasing specific growth rate comparable to the serum-containing medium and in almost the same high antibody production regardless of the number of generations.

While CHO cell lines have conventionally been grown as attached cultures they will also grow in free suspension; this has allowed for simple scale up in stirred tank and airlift bioreactors.

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. For best results, only cells that have been recently split to 2×10 6 cells/ml Hi Rachel! I know that CHO cells can be adapted for either adherent or suspension culture, depending on the desired application.

Expand CHO-S cultures by seeding shake flasks at 1 to 2 x 105 viable cells/mL or adherent cultures at 1 to 2 x 103 cells/cm2 by diluting cells in pre-warmed growth medium. See Subculturing Cells to maintain and subculture CHO-S cells in suspension or adherent culture. Note: We recommend subculturing cells for a minimum of 3 passages CHO cells can grow in chemically deﬁned and serum-free media enabling standardization of the production process and Good Manufacturing Practices compliance [2]. Also impor-tant, CHO cells are easily adapted to grow in suspension culture, which is preferred for large-scale culture [3]. The gly- Chinese Hamster Ovary (CHO) cells have emerged as the gold standard in the production of biologics.

They are easy to cultivate and are capable of growing at high cell densities (>2×10 7 cells mL −1) in single-cell suspension culture if provided with Suspension-adapted Chinese hamster ovary cell (CHO-S) cultures are widely used in biotechnological production of recombinant proteins.

2017-09-26 CHO cells possess several properties that have proven advantageous to their application in recombinant protein manufacturing. They are easy to cultivate and are capable of growing at high cell densities (>2×10 7 cells mL −1) in single-cell suspension culture if provided with Suspension-adapted Chinese hamster ovary cell (CHO-S) cultures are widely used in biotechnological production of recombinant proteins. In fact, such special cell lines have become the standard for this type of biopharmaceutical production ().The reasons for that include their fast reproduction, high protein expression rate compared with other eukaryotic cells and, above all, the glycosylation Chinese hamster ovary (CHO) cells are an epithelial cell line derived from the ovary of the Chinese hamster, often used in biological and medical research and commercially in the production of recombinant therapeutic proteins.

Hi Rachel! I know that CHO cells can be adapted for either adherent or suspension culture, depending on the desired application. Have you started using a new batch of flasks or plates recently? Suspension-adapted Chinese hamster ovary cell (CHO-S) cultures are widely used in biotechnological production of recombinant proteins. In fact, such special cell lines have become the standard for this type of biopharmaceutical production (1). 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.
