CHO cell lines Chinese Hamster Ovary Cell Culture | Nikon's MicroscopyU. Schematic diagram of 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”.

HEK and CHO cells is presented. Surfactants are commonly used cell culture medium components for reducing shear stress in non-static suspension culture. Despite the preferred application of poloxamer 188, there is an ongoing discussion about surfactant-related process deviations. Furthermore, surfactants have shown to interact with polyplexes

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. L-glutamine, hypoxanthine Suspension cell culture methodology Adaptation to suspension culture was carried out using multiple methods (Table 1). Each method is comprised of a commercially-available base medium to which standard cell culture supplements such as HI-FBS and L-glutamine were added according to the manufacturer’s adaptation protocol.

The first culture lasted 22 days and the second culture, 18 days. The temperature was gradually decreased from 37 °C to 31 °C during the bioprocesses. In the 1980s, CHO cells were usually cultured in batch fermentation with a cell concentration of 3 million cells per milliliter and a product titer of 100 mg l −1.

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.

Swirl Objective: To domesticate adherent Chinese hamster ovary (CHO) cells into suspension CHO cells (CHO-S) cultured in serum-free medium,and evaluate the application of the CHO-S cells in antibody expression. Methods: Adherent CHO cells were domesticated into CHO-S cells through suspension culture and gradually decreasing the serum concentration, and eventually the cells were cultured in serum Figure 1: Infographic depicting general steps in the cell line adaptation process.
