FAQs - CHO Media
CHO cells are typically cultured in Ham's F12K or DMEM supplemented with 10% FBS. However, in commercially manufacturing, chemically defined and animal-derived component-free media are recommended for culturing Chinese hamster ovary (CHO) cell lines for consistency and quality assurance of the end product.
CHO cells became popular to study genetics because they have a low chromosome number. As a result, CHO cells have been used for a long time and we know a lot about their genetics and growth characteristics.
Serum-free media are media designed to grow a specific cell type or perform a specific application in the absence of serum. Serum-free media are an important tool allowing scientists to culture cells with a defined set of conditions while minimizing variables.
Some advantages of using serum-free media include easier purification and downstream processing, precise evaluations of cellular function, increased definition, more consistent performance, and a more consistent supply chain.
