Some recombinant glycoproteins (e.g. from CHO cells) contain small amounts of undesired glycan structures with the Gal?1-3Galß1-4GlcNAc–motif which are assumed to be antigenic in humans. TheraProteins provides appropriate reference oligosaccharides for detection of these glycans at early stages of biotech process set-up with mammalian expression systems and to quantitate them during downstream processing steps and in the final drug substance. | |
