Mismatch base pair detection by fluorescence spectral change upon addition of metal cation--toward efficient analysis of single nucleotide polymorphism.

Abstract excerpt

Addition of mercury (II) cation to fluorescent-labeled duplex involving a T:T mismatch base pair and silver (I) cation to fluorescent-labeled duplex involving a C:C mismatch base pair significantly changed the fluorescence intensity, but no significant change in the fluorescence intensity was observed for duplexes involving the other base pairs. The fluorescence spectral change upon addition of the metal cation...
