General description

The GS System™ 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.

Application

GS Supplement 50X has been used to as a supplement for culture media to grow GS-NS0 mouse myeloma cells.
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.

Packaging

Contains (mg/L): L-alanine 450.0, L-asparagine · H2O 4261.0, L-aspartic acid 650.0, L-glutamic acid 3750.0, L-proline 575.0, L-serine 500.0, adenosine 350.0, guanosine 350.0, cytidine 350.0, uridine 350.0, and thymidine 12.0

Preparation Note
