Key oligosaccharides and their protein glycoconjugates used in this study. Additional glycoconjugates are shown in the Supporting Information and carry the prefix “S”: A type hexa- and trisaccharide 1 and 4, and their protein conjugates 2, 3, and 5; M type di- and tetrasaccharide BSA glycoconjugates 6 and 7; heptasaccharide 8 carries a terminal rhamnose residue equipped with an amino tether to effect attachment of an A type hexasaccharide repeat to protein via the terminal nonreducing end; as in BSA and tetanus toxoid conjugates 9 and 10.
