Abstract:
A novel class of azo-guanidine compounds is introduced in this article. The novel compound 2-(2-hydroxyphenyl)-1-(phenylamino)-3-(phenylimino)guanidine (AG) was synthesized and well characterized by using different analytical instrumental techniques like elemental analysis, FTIR, (1)H and (13)C NMR, UV-Visible spectroscopy and cyclic voltammetry. The new compound was found interacting with DNA and shows clear color change in the solution. The AG-DNA complex was qualitatively and quantitatively characterized with UV-Visible spectroscopy and cyclic voltammetry. Electrostatic mode of interaction, clear color change and moderate binding constant (K(b)=10(4)) indicate its potential use as DNA staining agent.

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...
