The sialyloligosaccharide, NeuAcα2-3Galβ1-3GlcNAcβ1-3Galβ1-4Glc (LS-tetrasaccharidea), a minor component of human milk, is obtained in relatively large quantities from autohydrolysates of the major milk disialyloligosaccharide, NeuAcα2-3Galβ1-3[NeuAcα2-6]GlcNAcβ1-3Galβ1-4Glc (disialyllacto-N-tetraose). Rabbits immunized with an oligosaccharide-protein conjugate prepared from keyhole limpet hemocyanin and LS-tetrasaccharideaproduce antibodies directed against the corresponding oligosaccharide alditol. The anti-LS-tetrasaccharideasera bind3H-labeled LS-tetrasaccharideain a direct-binding radioimmunoassay on nitrocellulose filters. The specificities of these antibodies are determined by comparing inhibitory activities of structurally related oligosaccharides. Strong hapten-antibody binding (Ka> 106m−1) requires sialic acid linked α2–3 to the nonreducing terminal galactose residue of reduced lacto-N-tetraose (Galβ1-3GlcNAcβ1-3Galβ1-4GlcOH). Specificities of antibodies prepared against keyhole limpet hemocyanin conjugates of LS-tetrasaccharideb(Galβ1-3[NeuAcα2-6]GlcNAcβ1-3Galβ1-4Glc) and LS-tetrasaccharidec(NeuAcα2-6Galβ1-4GlcNAcβ1-3Galβ1-4Glc) differ only slightly from rabbit antibodies prepared against the corresponding bovine serum albumin conjugates described previously [D. F. Smith and V. Ginsburg (1980)J. Biol. Chem.255, 55–59].
