A Nucleobase that Releases Reporter Tags upon DNA Oxidation

Abstract

We have developed a novel nucleosbase, edaG, that efficiently releases various reporter units upon one-electron oxidation. The edaG-selective degradation of ODNs was achieved by various mild oxidizing agents. The oxidant-dependent molecular releasing technique is quite useful not only for DNA-based drug releasing systems but also for the detection of long-range hole transport through DNA without time-consuming analysis
