Summary for Patent: 9,567,578

Title:	Cell line containing a knockout of the glutamine synthetase (GS) gene and a method of producing target proteins using a GS knockout HEK293 cell line
Abstract:	The present invention relates to a novel GS (glutamine synthetase) gene knock out transgenic HEK293 (human embryonic kidney 293) cell line and a production method of a target protein using the said transgenic HEK293 cell line. Particularly, the present inventors eliminated the expression of GS in the HEK293 cells in order to overcome a barrier of the cell line selection caused by the over-expression of GS, for producing a target protein by GS/MSX system, by which the efficiency of the cell line selection for the high production of a target protein would be increased and accordingly the protein production by the selected cell line would be increased, suggesting that the human originated transgenic HEK293 cell line could be efficiently used for the production of a target protein.
