DefinitionA polysaccharide derivative with a repeating unit consisting of α-D-galactosyl, 2-O-acetyl-β-L-rhamnosyl, β-D-glucosyl and N-acetyl-β-D-galactosaminyl residues linked sequentially (1→3), (1→4) and (1→3), to the galactosyl and N-acetyl-β-D-galactosaminyl residues of which are attached respectively a β-D-galactosyl residue and an N-acetyl-α-D-glucosaminyl-(1→2)-α-L-rhamnosyl disaccharide unit via (1→2) and (1→4) linkages respectively, with all repeating units being linked (1→6). The repeating unit corresponds to that of the capsular polysaccharide of Streptococcus pneumoniae serotype 7F (ST7F).
