Abstract
Provided are a method for preparing a glycan from a glycoprotein, and a kit and a device for preparing a glycan from a glycoprotein. The method includes (I) a step of obtaining a glycan-containing sample by bringing a glycan releasing solution that contains a hydroxylamine compound and a basic reagent into contact with the glycoprotein and releasing the glycan from the glycoprotein; (II) a step of adsorbing a glycan having a length of a monosaccharide or more on a purifying agent for purifying the glycan by bringing the glycan-containing sample into contact with the purifying agent, which is composed of a compound having a betaine structure; and (III) a step of eluting the glycan from the purifying agent.
