By Qi Liu, Bernie Sweeney, Marc Feary

GS Effex®, derived from Lonza’s leading GS Xceed® cell line, produces molecules that are 100% free of fucose and demonstrate increased potency, without compromising on the titers, growth, stability and product quality that GS Xceed® is known for.

Lonza's GS Gene Expression System® is widely used for the expression and manufacturing of biologics. The latest addition to the GS® toolbox, the GS Effex® cell line, is derived from the industry-known GSXceed® CHOK1SV GS-KO® cell line.
