GlycoExpress® (GEX®) technology is a well-established human expression platform for the screening and production of biotherapeutics. By contrast with other human cell lines (e.g., HEK293 and Per.C6) GlycoExpress® expression platform consists of a toolbox of glycoengineered cell lines optimized for producing biotherapeutics with desired glycan structures to improve their clinical performance.

Glycotope’s GEX® technology provides an established expression platform proven for different biopharmaceuticals:

• Antibodies of different isotypes (e.g., IgG, IgM, IgA)
• Defucosylated antibodies
• Bispecific antibodies/fragments (e.g., NK cell/T-cell recruiters)
• Difficult-to-express and complex glycosylated proteins
• Blood factors (e.g., FVII)
• Protein hormones (e.g., FSH, HCG)
• Fusion proteins with extended serum half-life
• Enzymes (e.g., for enzyme replacement therapy).
