Glycoconjugate probes containing a core-fucosylated N-glycan trisaccharide for fucose lectin identification and purification.

Glyco-PAMAM dendrimers and glyco-agarose beads bearing a core-fucosylated N-glycan trisaccharide GlcNAcβ1,4(Fucα1,6)GlcNAc or a non-fucose disaccharide GlcNAcβ1,4GlcNAc were successfully synthesized and characterized by monosaccharide analysis with HPAEC-PAD technique. These glycoconjugates as fucose lectin probes were applied in fucose-specific lectin detection and purification. The model fucose lectin AAL indicated binding activity with the FITC-labeled PAMAM carrying core-fucose trisaccharide.
