Sulfated trisaccharide 6-Su-6’SLN was synthesized as described previously (Pazynina et al., 2008). Biotinylated sialoglycopolymers (~30 kDa) with different saccharide residues were synthesized as previously described (Bovin et al., 1993) and were used to characterize the receptor specificity of H1N1 influenza A viruses.
