PROBLEM TO BE SOLVED: To provide a sugar chain structure analysis method for identifying a sugar chain having a branching structure, etc. as a structural isomer. SOLUTION: This sugar chain structure analysis method is used for isotope-labelling sugar of part of a sugar chain specimen to be analyzed, capable of having a structural isomer, and performing mass spectrometry on an obtained isotope-labelled sugar chain. Preferably, the chain specimen to be analyzed has branching sugar chains and the sugar chains have the same sugar chain arrangement as each other. Further, it is preferable that end sugar residual groups of the sugar chains are isotope-labelled by using<SP>13</SP>C. COPYRIGHT: (C)2005,JPO&NCIPI
