23994266-3	2013	In the glutamine synthetase (GS)-CHO expression system, selection of top-producing cell lines is based on controlling the balance between the expression level of GS and the concentration of its specific inhibitor, l-methionine sulfoximine (MSX).	L-Methionine sulfoximine	214-238	glutamine synthetase	Cricetulus griseus	7-27
