Sugar chain-capturing substance and use thereof

糖链捕获物及其用途

Abstract

The present invention provides a method for preparing a sample characterized by binding a substance A containing a hydrazide group 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 thereby to enable the separation and purification of the sugar chain and/or the sugar derivative for an analytical sample from a biological sample containing the sugar chain and/or the sugar derivative by a simple operation.
本发明提供了样品的制备方法,其特征是通过在物质A的酰肼基团与糖链和/或糖衍生物的还原末端之间形成腙,使包含酰肼基团的物质A与糖链和/或糖衍生物相结合,从而通过简单的操作从包含糖链和/或糖衍生物的生物样品中分离和纯化糖链和/或糖衍生物以获得分析样品。
