Abstract
A novel fluorescent DNA probe containing pyrene-labeled C8 alkylamino-substituted 2′-deoxyguanosine was designed in order to discriminate single stranded and double stranded regions in DNA. This fluorescent sensor was used for the design of practically useful 3′- and 5′-ends free self-quenched molecular beacon (MB). Unique MB detectable by pyrene excimer fluorescence was also demonstrated.
