| Research Abstract |
To develop a new detection method of methylated DNA, an artificial protein has been developed that contains the zinc finger motif as a DNA-binding moiety as well as an osmium complex since the latter can bind preferentially to a methylcytosine rather than the unmethylated counterpart. Based on detailed investigation of osmium complexation with a methylcytosine, the novel protein has been synthesized via a solid-phase synthesis method and its binding ability toward methylated DNA molecules was evaluated.
