Materials and methods. Calf thymus DNA–D-1501 (“Sigma”, USA), AO (“Sigma”, USA),
NaCl, Na-citrate, EDTA (ethylenediamintetraacetate)(chemically pure) were used in …

In this work the formation of the ligand-DNA complexes by different modes using absorption
and fluorescence spectroscopy methods has been investtigated. Comparison of the …

Difference absorption spectra (complex-sum of the initial reagents) are obtained in the
visible and longwave UV region for the system of actiflavine and DNA in a number of cases …

The presetit, communication reports observation of differences in the fluorescence spectra of
acridine orange (AO) intercalated into DNA of varying base composition. These spectral …

To confirm the nature of the binding of acridine orange (AO) with DNA, a
fluorospectrophotometric study was made on the AO-DNA system as well as on the …

The degree of binding of acridine orange to DNA, native or denatured, has been determined
by equilibrium dialysis in 0.1 M and 0.001 M NaCl at 20°. The nature of the binding process …

Interaction of ethidium bromide (EtBr), acridine orange (AO) and non-intercalator methylene
blue (MB) with DNA as well as interaction of EtBr and MB with single-stranded synthetic …

The interaction between acridine orange (AO) and diluted and concentrated solutions of
DNA, DNP systems and chromatin suspension at the physiologic ionic strength was …

Comparision of theoretical and experimental data of ethidium bromide (EtBr) binding to DNA
suggested that this ligand can complex with DNA by several different types of interactions [1 …

The mathematical approach has been applied in order to analyze the isosbestic point on the
absorption spectra of DNA-ethidium bromide (EtBr) complexes and it was shown that the …
