O -phosphono-β- d - manno -2-octulopyranosid)onate were prepared and copolymerized with acrylamide to give multivalent haptens, which were used in immune inhibition assays. The monoclonal antibody A 20, directed against α-pyranoside Kdo residues, did not react with these compounds, except with heptulosonic acid derivative 6 , thus proving that the terminal hydroxymethyl group of Kdo is not required
