    Abstract:
    We have determined the structures of six oligosaccharides isolated from human milk using a monoclonal antibody, MSW 113. The isolation involved affinity chromatography on a column of the immobilized monoclonal antibody and high-performance liquid chromatography. From the results of 500 and 600 mHz 1H NMR spectroscopy and fast atom bombardment-mass spectrometry their structures were deduced to be: [formula; see text] Two of these oligosaccharides, numbers 4 and 5, have not previously been described. All of them bound to MSW 113, but their reactivities are weaker than those of sialyl-Le(a) oligosaccharides. The results indicate that MSW 113 reacts with oligosaccharides with the mono- and disialyl-Le(a), and other sialyl type 1 structures.
