An aminopropyl linker at the reducing end enables printing onto microscope slides. One of a series of substructures of the Helicobacter pylori O6 O-antigen tridecasaccharide O-antigen used for its immunological evaluation. It is a trisaccharide derivative and a glycoside. It is functionally related to an alpha-L-Fuc-(1->2)-beta-D-Gal-(1->4)-[alpha-L-Fuc-(1->3)]-beta-D-GlcNAc-(1->3)-beta-D-Gal-(1->3)-alpha-DD-Hep-(1->3)-alpha-DD-Hep-(1->3)-alpha-DD-Hep-(1->3)-alpha-DD-Hep-(1->3)-alpha-DD-Hep-(1->6)-alpha-DD-Hep-(1->2)-alpha-DD-Hep-(1->2)-alpha-DD-Hep-O[CH2]3NH2."}]
