Recombinant Mouse Antibody (S54-10) is capable of binding to Kdo. MAb S54-10 bound to the C. psittaci specific structures to a similar extent as S73-2 but exhibited lower affinity for all other antigens tested. S54-10 did not differentiate between antigens containing the branched Kdo tetrasaccharide or the (2→4)-(2→4)-linked trisaccharide, but did bind to the 2→8-2→4-linked trisaccharide with weaker affinity than S73-2. S54-10 bound with very high affinity to Kdo(2→4)Kdo(2→4) and bound o nly weakly to the Kdo(2→8)Kdo(2→4) trisaccharide. Thus S54-10 is highly specific for the Kdo(2→4)Kdo(2→4) trisaccharide.
