Research Abstract	MUC2 mucin (glyco)peptides with fifty-six patterns of N-acetylgalactosamine (GalNAc) residue attachment were synthesized and immobilized on the plate. Binding affinities of VVA-B4, a plant lectin, toward GalNAc attached MUC2 peptides were measured using ELISA. The results suggested that the affinity was defined by the sites of GalNAc attachment on the peptides. The plate with GalNAc attached MUC2 peptides was successfully developed and this made possible for measuring the affinities of parasite lectins toward GalNAc attached MUC2 peptides.
