  • Title: Modulation of base selectivity for a base-discriminating fluorescent nucleobase by addition of mercury ion.
    Author: Okamoto A, Ochi Y, Saito I.
    Journal: Bioorg Med Chem Lett; 2005 Oct 01; 15(19):4279-81. PubMed ID: 16046124.
    Abstract:
    We altered the fluorescence emission selectivity of a base-discriminating fluorescent base, (Py)U, from A-selective to T-selective by the addition of mercury ion. The strong fluorescence from a duplex containing the (Py)U/T base pair was specific to the mercury ion among divalent metal ions, providing a unique method for sensing mercury ions in aqueous solutions.
