[Resonance light scattering study on the interaction of Victory blue-B with deoxyribonucleic acid and application to DNA assay].

The enhancement of the Resonance Light Scattering (RLS) due to Victory blue-B on the molecular surface of DNA in alkalescence solution was studied. A method of resonance light scattering was developed to determine DNA. Deoxyribonucleic acid (DNA) was studied in the range of pH 9.
