<P>PROBLEM TO BE SOLVED: To provide an oligosaccharide or its derivative having a new structure, particularly to provide an oligosaccharide or its derivative used for the standard sugar chain in the structural analysis used as a clue for elucidating unknown sugar chains. <P>SOLUTION: There is provided an oligosaccharide comprising a structure having (1) four or more N-acetyllactosamines (Gal-GlcNAc), (2) one or more structures branching at galactose, and (3) two or more fucoses, or its derivative. Alternatively, there is provided an oligosaccharide comprising a structure having (1) four or more N-acetyllactosamines (Gal-GlcNAc) and (2) one or more lactoses (Gal-Glc), or its derivative. <P>COPYRIGHT: (C)2008,JPO&INPIT |
