GALAXY Database and Pyridylaminated Oligosaccharide Library

A wide array of standard oligosaccharides is a valuable glycomics tool for systematic and detailed analyses of structures and functions of sugar chains. The multi-dimensional HPLC mapping method developed by Takahashi and co-workers enables us to isolate N-linked oligosaccharides as pyridylaminated (PA) derivatives, discriminating isomeric structures. Therefore it becomes extremely useful not only for identification and profiling of N-glycans but also for purification and library formation of PA-oligosaccharides (Tomiya et al. 1998; Takahashi et al. 2007). Based on the accumulated 2-D/3-D HPLC data for more than 500 different structures of N-glycans, we developed a web application, GALAXY (Glycoanalysis by the three axes of MS and chromatography), for effective utilization of the multi-dimensional HPLC map (Takahashi and Kato 2003).
