Title:
METHOD FOR PREPARING SAMPLE FOR ANALYSIS AND METHOD FOR ANALYZING SAME
Document Type and Number:
WIPO Patent Application WO/2023/243136
Kind Code:
A1
Abstract:
Provided is a method for analyzing an O-linked sugar chain that has been undergone sialic acid linkage-specific modification, the method comprising: a modification step for adding a modifier, which performs sialic acid linkage-specific modification on the O-linked sugar chain, to a sample containing a glycoprotein to which the O-linked sugar chain is linked; a release step for releasing, from the glycoprotein, the O-linked sugar chain that has been undergone the sialic acid linkage-specific modification; and an analysis step for analyzing the released O-linked sugar chain that has been undergone the sialic acid linkage-specific modification.
