This animal component-free medium is designed to support clonal survival and growth of Chinese Hamster Ovary (CHO) cell lines, with results comparable to the traditional method using 10% fetal bovine serum.

Features and Benefits

Developed to meet the needs of the biotechnology industry, this animal component-free medium is designed for single-cell cloning of recombinant CHO cell lines adapted to serum-free suspension culture.

Other Notes

Proprietary formulation containing inorganic salts, sodium bicarbonate, essential and non-essential amino acids, vitamins, trace elements, plant hydrolysates, and other organic compounds.
Does not contain antibiotics, antimycotics, L-glutamine, insulin, or transferrin.


Do not freeze. Protect from light. Several components of the medium are light labile and should not be exposed to light for lengthy periods of time.


Aseptically add 10 mL of 200 mM L-glutamine solution per 500 mL of medium prior to use.
