Abstract:
:A set of 15mer linear oligoDNA probes bearing a modified nucleoside conjugated with a polyamine/fluorescein/anthraquinone reporting moiety were synthesized. In a single-stranded form, the fluorescence generated by the excitation of fluorescein was efficiently quenched, while marked recovery of the fluorescence was observed when the probes formed duplexes with the fully complementary strand.
