Outline of Final Research Achievements |
Quantitation and identification of DNA adducts, which was induced by genotoxic compounds and their reactive metabolites, can be important for understanding the carcinogenic process and risk assessment. Sensitive methods have been used for the quantitation of DNA adducts because almost all of DNA adducts will be removed by inherent DNA repairing system, typically corresponding to a few adducts in million - billion normal 2’-deoxynucleosides. In this research, a more highly sensitive method than general one in liquid chromatography-mass spectrometry and capillary electrophoresis-mass spectrometry was studied. By optimizing each condition, we achieved an improvement in sensitivity by one order of magnitude in each system.
