Abstract

Structural glycomics (SG) plays a fundamental part of concurrent glycobiology aiming at comprehensive elucidation of glycan functions ( i.e. , functional glycomics) in the context of post-genome sciences. The SG project started in April 2003 and will continue for 3 years in the framework of NEDO (New Energy and Industrial Technology Organization) under the METI (the Ministry of Economy, Trade, and Industry), Japan. The main purpose of the project is the development of high-throughput and robust machines, which should greatly contribute to the structural analysis of complex glycans. In this chapter, 2 major research items, i.e. , (1) glycoproteomics, which enables comprehensive analysis of glycoproteins, and (2) "glycan profiling" by means of lectins, are described. For the latter, frontal affinity chromatography has been adopted as a starting tool for comprehensive analysis of the interaction of 100 lectins and 100 oligosaccharides under the concept of "hect-by-hect," which refers to 100 x 100.
