HPLC method for the determination of Fuc to Asn-linked GlcNAc fucosyltransferases

Mammalian cells often contain an enzyme which transfers fucose onto the reducing terminal GlcNAc (GlcNAc-1) of N-glycans with an α1,6-linkage. In plants, on the other hand, the fucose is transferred to GlcNAc-1 with an α1,3-linkage. Insect cells can exhibit both enzymatic activities. Hitherto, the activity of these fucosyltransferases has been determined by… (More)
