SUGAR CHAIN-CAPTURING SUBSTANCE AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a novel sugar chain-capturing substance, a method for preparing a sample using the sugar chain-capturing substance, and an analytical sample obtained by the method.

SOLUTION: The method for preparing a sample is provided, wherein a substance A including a hydrazide group is bound to a sugar chain and/or a sugar derivative via hydrazone formation between the hydrazide group of the substance A and the reducing end of the sugar chain and/or the sugar derivative. The separation and purification of the sugar chain and/or the sugar derivative for an analytical sample from a biological sample including the sugar chain and/or the sugar derivative is performed by simple operation.
