Dabsylated products (GnGnF3, GnGnF6, GalGalF, βGNβGNF) obtained from incubation with recombinant fucosyltransferases (AgFucTA, AgFucT6, AgFucTC) were split and incubated with hydrofluoric acid and α1,6-fucosidase from bovine kidney respectively. Core α1,3- and Lewis-type fucose residues demonstrated sensitivity towards hydrofluoric acid treatment, whereas core α1,6-fucose was only susceptible to bovine α1,6-fucosidase. Sensitivity towards a treatment is indicated by (+).
