Since the 2-D/3-D HPLC mapping technique was proposed for structural analyses of N-glycans, approximately 500 different structures have been elucidated. Based on the accumulated data, we developed a web application, GALAXY (Glycoanalysis by the three axes of MS and chromatography), to utilize the 2-D/3-D maps more effectively. This application will facilitate search of candidate structures satisfying 2-D/3-D HPLC and/or mass spectrometric data and enable us to predict coordinates of putative PA-glycans and to trace the effects of glycosidase treatments in a graphical manner.
