Harold J Jennings, Czeslaw Lugowski: Immunogenic polysaccharide-protein conjugates. Canadian Patents & Development, Alan A Thomson, October 26, 1982: US04356170 (188 worldwide citation)

Antigenic polysaccharides are modified to generate a terminally-located aldehyde group by controlled oxidation of vicinal hydroxyl groups, e.g. of unlinked terminal non-reducing sialic acid residues. In some cases where there is a reducing end group, e.g. of the type N-acetylmannosamine residue, it ...
