Definition:	An amino heptasaccharide consisting of a beta-D-Gal-(1->3)-beta-D-GlcNAc-(1->3)-beta-D-Gal-(1->4)-beta-D-Glc tetrasaccharide backbone, to the galactosyl residue distal to the reducing end is (1->4)-linked a beta-DGlcNAc residue, while Neu5Ac residues are linked to this same galactosyl residue and the GlcNAc residue via (2->3) and (2->6) glycosidic linkages respectively. An antigen for the monoclonal antibody RM2, it is used as a histological marker for prostate cancer.
