چکیده انگلیسی
We report on the control of the emission from a fluorophore fixed on DNA using the methylcytosine-selective addition of an osmium-bipyridine complex. We have synthesized DNA modified by a microenvironment-sensitive fluorophore, 2-dimethylamino-6-acyl-naphthalene. The emission from the fluorophore tethered to a probe DNA was effectively quenched by a methylcytosine glycol-osmium-bipyridine triad, which was located in the immediate neighborhood of the fluorophore. The discrimination of the cytosine methylation status at a methylation hot spot in the p53 gene was also executed using a well-designed fluorescent DNA probe.
