Abstract:
A new Mg2+-selective fluorescent probe P was synthesized and characterized. With optimal conditions, the proposed probe P showed good selectivity to Mg2+ compared to other common metal ions, and worked in a wide linear range of 5.0 × 10(-7)-6.0 × 10(-6) M with a detection limit of 1.7 × 10(-7) M Mg2+ in ethanol-water solution (9:1, v/v, 20 mM HEPES, pH = 10.0).

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
