Outline of Final Research Achievements

In this study, we aimed to establish a highly accurate, highly sensitive, and multiplex analytical method for a group of glycan tumor markers, including the isomers found by us, by the selected reaction monitoring (SRM) method of mass spectrometry. We investigated various parameters such as HPLC, pipe inner diameter, column, solvent, and elution conditions. As a result, we were able to find the conditions that enable multiplex analyses. The accuracy and sensitivity were also confirmed using several types of glycan mixtures.

Academic Significance and Societal Importance of the Research Achievements

現在、腫瘍マーカーの測定はすべて抗体を用いるELISA法が利用されている。ELISA法では、複数のマーカーを同時に測定することは困難で、個々のマーカーを別々に測定している。そのため、2-3種類のマーカーを選択している。一方、SRM法では多項目を同時に測定することが可能であり、今回の研究で、我々が見出した糖鎖腫瘍マーカー群を多項目同時に測定する方法を確立した。臨床検査において、腫瘍マーカー群のELISAと並ぶ測定方法になると期待される。
