SUGAR CHAIN-CAPTURING SUBSTANCE AND USE THEREOF

摘要

SUGAR CHAIN-CAPTURING SUBSTANCE AND USE THEREOF5 The present invention provides a method for preparing a samplecharacterized 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 enable10 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.15 Fig. 1
