title: Do endotoxins devoid of 3-deoxy-D-manno-2-octulosonic acid exist?
abstract: After treatment with aqueous, 50% hydrofluoric acid, a well-known dephosphorylating agent, the presence of 3-deoxy-D-manno-2-octulosonic acid (KDO), an essential and characteristic constituent of endotoxins, can be readily demonstrated in reportedly KDO-deficient bacterial lipopolysaccharides.
