Fluorescence probe sensitive to detect G-rich target strands through quenching.
Modified fluorescent probe U(F)AA AAT CTC CGC CGC has been synthesized using the nucleoside analogue 3'-O-(N,N'-diisopropylamino-2-cyanoethoxyphosphinyl)-5'-O-(4,4'-dimethoxytrityl)-2'-O-(dansyl-1-sulfonamidohexylaminocarbonyl)uridine for hybridization studies with perfectly matched (U/A) complementary and with DNA strand having similar G-rich telomeric units at the 3'-end. The thermal stability data and decrease in fluorescence intensity due to the presence of dG units clearly demonstrated the potential application of this approach in DNA diagnostics in homogeneous hybridization assays.
