Spectroscopic study on the interaction between sodium 9,10-anthraquinone-2-sulfonate and DNA
Sodium 9,10-anthraquinone-2-sulfonate (AQS) binds to the double helical DNA with a high affinity, as deduced from the absorption and fluorescence spectral data. The results of absorption spectra, KI quenching studies, competitive binding studies, and thermal denaturation experiments suggested the intercalative binding of AQS into DNA bases.
