The interaction of ethidium bromide with single-stranded synthetic and natural polynucleotides at high temperatures (t = 70 degrees C) and low pH values (pH 3.0) was studied. The isotherms of adsorption of ethidium bromide on single-stranded DNA were obtained. Two modes of binding of single-stranded DNA, strong and weak, were revealed. The values of the corresponding constants of interaction of this ligand and the number of bases per one binding site were determined.

UI MeSH Term Description Entries
D004277 DNA, Single-Stranded A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle. Single-Stranded DNA,DNA, Single Stranded,Single Stranded DNA
D004996 Ethidium A trypanocidal agent and possible antiviral agent that is widely used in experimental cell biology and biochemistry. Ethidium has several experimentally useful properties including binding to nucleic acids, noncompetitive inhibition of nicotinic acetylcholine receptors, and fluorescence among others. It is most commonly used as the bromide. Ethidium Bromide,Homidium Bromide,Novidium,Bromide, Ethidium,Bromide, Homidium
