THREE-BRANCHED SUGAR CHAIN ASPARAGINE DERIVATIVE, THE SUGAR CHAIN ASPARAGINE, THE SUGAR CHAIN AND THEIR PREPARATION METHODS

摘要

PROBLEM TO BE SOLVED: To provide a three-branched sugar chain asparagine derivative wherein an amino nitrogen in asparagine is modified with a lipophilic protective group, a biotin group or an FITC group, and its preparation method. SOLUTION: The three-branched sugar chain asparagine derivative wherein the amino nitrogen in asparagine is modified with a lipophilic protective group, a biotin group or an FITC group is represented by formula (1) (wherein R1and R2are different from each other and are each a hydrogen atom or galactose; and Q is a lipophilic protective group, a biotin group or an FITC group).
