 note = {P(論文), I developed novel analytical methods of Asn-linked neutral- and sialyloligosaccharides,and O-linked oligosaccharides derived from glycoprotein swith use of high performance liquid chromatography ; (HPLC). The oligosaccharides were labeled with a ultra-violet absorbing compound, p-aminobenzoic ethyl ester (ABEE), by reductive animation to obtain high sensitivity of detection and sufficient resolution on HPLC. The ABEE derivatives of the neutral oligosaccharides can be efficiently separated by a combination of normal-phase and reversed-phase HPLC and the anionic oligosaccharides by a combination of anion-exchange and reversed-phase HPLC. These methods have been successfully adapted for the analysis of the oligosaccharides from some bioactive glycoproteins. I) A sea squirt H-antigen was found to contain the following allergenically active O-linked oligosaccharides: GalNAc β1-4 (GalNAc α1-2 Fuc α1-3) GlcNAc β1-3GalNAc-ol, GalNAc β1-4GlcNAc β1-3 (GalNAc β 1-4 GlcNAc β1-6) GalNAc-ol, GalNAc β1-4 (±Fuc α1-3) GlcNAc β1-3[GalNAc β1-4 (Fuc α1-3) GlcNAc β1-6]GalNAc-ol, and GalNAcβ1-4 (GalNAc α1-2Fuc α1-3) GlcNAc β1-3[GalNAc β1-4 (GalNAc α1-2Fuc α1-3) GlcNAc β1-6]GalN Ac-ol. Disaccharide units GalNAcα1-2Fucα1-, and GalNAc β1-4GlcNAc β1- are considered to be the allergenically-specific epitopes in this sea squirt asthmatic allergy. II) Hen egg-yolk immunoglobulin was found to contain three types of Asn-linked oligosaccharides; monoglucosylated oligomannose type oligosaccharides with structures of Glcα1-3Man_<7-9>GlcNAc-GlcNAc, a series of oligomannose oligosaccharides, Man_<5-9>GlcNAc-GlcNAc, and biantennary complex type oligosaccharides with the core structures Manα1-6 (Manα1-3)(±GlcNAc β1-4)Man β1-4GlcNAc β1-4(±Fucα1-6) GlcNAc. The strucrutal feature of the oligosaccharides was quite different from that of mammalian immunoglobulin. The glucosylated oligoaccharides, Glc_1-Man_<7-6> GlcNAc_2, have not previously been reported in mature glycoproteins from any source. III) Predominant oligosaccharides accumulated in the kidney of a calf with β-mannosidosis were found to be Manβ1-4GlcNAc and Man β1-4GlcNAc β1-4GlcNAc. As expected in a β-mannosidase deficiency state, the terminal residue of the accumulated oligosaccharides was a β-linked mannose. The structures of the accumulating oligosaccharides were identical to those accumulated in caprine β-mannosidosis tissues.},
