Abstract
A method for preparing an analytical sample for analyzing a glycan contained in a sample includes: performing a first reaction so that when sialic acid is linked to the glycan, sialic acid of a first linkage type is lactonized and modification different from lactonization is performed on sialic acid of a second linkage type different from the first linkage type; performing a second reaction to ring-open a lactone formed in the first reaction; and performing the first reaction again.
