Abstract

The analysis of fluorescence quantum yields reveals that bound proflavine does not fluoresce unless it is intercalated between two adjacent AT pairs. The results of 9-aminoacridine suggest that two adjacent AT pairs next to GC pairs may be still quenching sites for the dye or the heterogeneity of the dye binding may occur.
