First Claim
Patent Images
1. A method for liberating sugar chains from a glycoprotein having proteins and at least one of N-binding sugar chains and O-binding sugar chains, the at least one of N-binding sugar chains and O-binding sugar chains being bound to the proteins through an N-glycosidic bond or an O-glycosidic bond, respectively, the method comprising:
- a step of bringing a reaction solution which contains hydroxylamines (a) and a basic reagent (b) into contact with the glycoprotein and cleaving the N-glycosidic bond or the O-glycosidic bond, to obtain a mixed solution of the sugar chains liberated from the glycoprotein and the reaction solution,wherein, in the step of bringing the reaction solution into contact with the glycoprotein, a pH of the reaction solution is in a range of 8 to 14.
