Application

EX-CELL CD CHO is a chemically defined, animal-component free, serum-free medium developed for the long-term growth of Chinese Hamster Ovary (CHO) cells and expression of antibodies or protein products in suspension cell culture. CHO suspension cultures can be subcultured directly into EX-CELL CD CHO from serum-supplemented or serum-free medium with little or no adaptation. EX-CELL CD CHO is formulated without hypoxanthine, thymidine or L-glutamine, making it an appropriate medium for selection systems such as DHFR- and Glutamine Synthetase (GS System™). For applications that do not require the selective pressure of a hypoxanthine/thymidine (HT)-deficient medium, we recommend the use of EX-CELL CD CHO with hypoxanthine and thymidine (Catalog No. 14361C).

MGAT1 adds N-acetylglucosamine to the Man5GlcNAc2 (Man5) structure. Goh et al. reported increased sialylation after restoring MGAT1 function in MGAT1 deficient CHO cells.

The Glutamine Synthetase (GS) expression system does not typically require multiple rounds of amplification to isolate high-producing clones (Brown, 1992).

In the present study, we have identifi ed species-specifi c housekeeping genes (HKGs) for Chinese Hamster Ovary (CHO) cells using data from microarray gene expression profiling.

A signal peptide is a 5-30 amino acid (aa) peptide present at the N-terminus of secretory proteins.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
