[Fluorescence characteristics of DNA complexes with dyes of the bis-benzimidazole series].
Fluorescence characteristics of DNA-specific dyes of bis-benzimidazole type in a wide range of pH and r = C/P were investigated. Fluorescence spectra of DNA complexes with bis-benzimidazoles have elements of a structure, which may result from a superposition of the spectra of dye molecules in different protonization group states that form different types of complexes with DNA. Experimental data do not contradict the idea of bis-benzimidazole dye binding into the minor groove of DNA. Bis-benzimide molecules in the deprotonization state have a major affinity to DNA.
