| Research Abstract |
We have devised a method for glycome analysis by using on-line two-dimensional HPLC. N-linked oligosaccharides, mucins and glycosaminoglycans were separated simultaneously by the HPLC. We applied this method to a genetically tractable model organism, Drosophila melanogaster. In addition to this chemical analysis, western-blot analysis by use of lectin staining and immunostaining provides attractive tools to further understanding of basic physiological functions of glycoconjugates. Thus, we carried out glycoconjugate profiling of Drosophila by 1D or 2D-electrophoresis with western-blot analysis followed lectin staining and immunostaining. Drosophila glycoconjugates were well characterized by SBA, ConA and WGA lectins and the method was applied to flies bearing mutations in glyco-genes. Furthermore, proteoglycans were profiled by western-blot analysis with immunostaining. These methods are planning to be employed in the proteo-glycomics study.
