Schematic structure of the HSA conjugates of the synthetic saccharides. The tetrasaccharide repeat unit of the O-SP of S. dysenteriae type 1, 3)-α-l-Rhap-(1→2)-α-d-Galp-(1→3)-α-d-GlcpNAc-(1→3)-α-l-Rhap-(1→, is shown with the spacer at its reducing end. The tetrasaccharides for the octamer, dodecamer and hexadecamer were added to the nonreducing end in prefabricated form.
