The GS System(TM) uses the Glutamine synthetase (GS) gene as a selectable marker for the expression of recombinant proteins in mammalian cells, especially NS0 and CHO cells. The system has been shown to have significant advantages with respect to speed and efficiency of cell line development and has resulted in high productivity for antibodies and other recombinant proteins.
Synonyms: GSEM Supplement; Glutamine synthetase expression medium supplement
MDL Number: MFCD00677096
Storage: -20C
Application: The glutamine synthetase (GS) system is used to express recombinant proteins from mammalian cells. Glutamine-dependent cells transfected with a glutamine synthetase gene can be selectively grown in a suitable glutamine-deficient medium.
