SUGAR CHAIN LIGAND COMPOSITE AND METHOD OF ANALYZING PROTEINWITH THE LIGAND COMPOSITE
A novel ligand composite which is effectively utilizable for analyzing a function of a protein
a ligand-supporting object
and a method of analyzing a protein. The ligand composite has a structure which comprises: a linker compound having a structure represented by the following general formula (1) : (wherein n and p each is an integer of 0 to 6) in which X is a structure comprising one, two, or three hydrocarbon derivative chains which have an aromatic amino group at the end and may have a carbon-nitrogen bond in the main chain, Y is a hydrocarbon structure containing one or more sulfur atoms , and Z is a linear structure comprising a carbon-carbon bond or carbon-oxygen bond
and a sugar which has a reducing end and is bonded to the linker compound through the aromatic amino group.
