Product Overview

Chinese hamster ovary (CHO) cells are an epithelial cell line widely used in research and commercial applications in producing recombinant therapeutic proteins. Other applications include genetic testing, toxicity screening, cell viability, and gene expression.

Our K1 subclone of a parental Chinese hamster ovary (CHO) cell line has been optimized for protein production. The cell line has been adapted to grow under suspension and adherent cultured conditions. Cell growth has been further adapted to expand under serum-free conditions using our companion CHO media.

Vial contains approximately 500,000 cells. Shipped with dry ice.

Cell Origins
The parental CHO cell line was originated by Puck in 1957. K1 line was subcloned from this line and deposited at ECACC in 1985. A vial of the ECACC-derived CHO K1 line was purchased by CET and further adapted for suspension and chemically-defined media.
