THREE-BRANCHED SUGAR-CHAIN ASPARAGINE DERIVATIVES, THE SUGAR-CHAIN ASPARAGINES, THE SUGAR CHAINS, AND PROCESSES FOR PRODUCING THESE

摘要

A three-branched sugar-chain asparagine derivative represented by the formul a (1) in which the nitrogen of an amino group of asparagine has been modified with a lipid-soluble protective group, biotin group, or FITC group; a three- branched sugar-chain asparagine derivative which is the three-branched sugar - chain asparagine derivative having at least one fucose bonded to an N- acetylglucosamine on the non-reducing end group side of the sugar-chain asparagine; these sugar-chain asparagines; and the sugar chains. (1) [In the formula, Q is a lipid-soluble protective group, biotin group, or FITC group. ]
