title: Development of fluorescence-labeling method for methylcytosine with metal complexation.
abstract: We report a methylcytosine-selective fluorescence labeling. An amino-modified bipyridine was prepared and used as an osmium ligand for methylcytosine-selective oxidation. Different fluorophores were easily incorporated to the modified methylcytosine site through an amide formation of the ligand amino group after osmium complexation.
