Method of measuring the interaction between the sugar chain and the biological substance, the method of evaluating carbohydrate selectivity of biological substances, the screening method of the biomaterial, and the method for patterning biological substances, and to perform these methods Kit

摘要

This invention provides a method of screening or patterning a biomaterial in terms of their specificities to sugar chains by performing real-time and comprehensive measurement of an interaction between sugar chains and the biomaterial concurrently with a very small amount of the biomaterial without labeling. It is a method of measuring an interaction between a biomaterial and a sugar chain(s), the method including: bringing a solution containing the biomaterial in contact with a ligand carrier, the ligand carrier including a support whose surface includes a metal, and a ligand conjugate(s) immobilized independently on the surface, the ligand carrier carrying the ligand conjugate(s) in such a manner that 1 to 500 kinds of the ligand conjugate(s) is immobilized per cmSUP2/SUP, and each ligand conjugate having a structure in which a sugar chain is bonded with a linker compound having a sulfur atom, and the biomaterial being at least one selected from the groups of proteins, viruses, cells, microorganisms, liposome, and micelles.
