Chinese Hamster Ovary (CHO) cells are a popular workhorse for production of recombinant therapeutic proteins. Amenable to both adherent and suspension culture, CHO cells offer versatility in growth platform that is favorable to the end user’s requirements.

In this Tips from the Bench, we highlight factors that differentiate adherent and suspension CHO cell cultures. Also, we describe a simple protocol for transitioning adherent CHO cells to suspension growth (and serum-free medium, if required).

A common question we encounter is: how can I extend CHO cell viability through the process of protein production? One common practice to maintain higher viability is to shift cell cultures to mild hypothermic conditions, e.g. 37°C to 32°C. Here, we discuss a hot (er… cold?) tip involving the CHOgro® High Yield Expression System, which also supports additional flexible protocol options for researchers who cannot shift cultures to 32°C or who desire extended cellular viability beyond one week following transfection.
