Definition A polysaccharide derivative with a pentasaccharide repeat unit consisting of α-D-glucosyl, 2-O-acetyl-α-L-rhamnosyl and N-acetyl-β-D-glucosaminyl residues all linked (1→3), to the α-glucosyl residue of which are attached a β-D-glucosyl residue and an α-L-rhamnosyl residue via (1→6) and (1→3) linkages respectively, with all repeat units being linked (1→4). The repeat unit corresponds to that of the native Escherichia coli serotype O25B O-antigen.
