Toxic Interaction of Thionine to Deoxyribonucleic Acids: Elucidation of the Sequence Specificity of Binding with Polynucleotides

, 2010
The sequence specificity of the intercalative DNA damage of the phenothiazine dye thionine has been investigated by absorbance, fluorescence, circular dichroism and viscosity studies using four synthetic polynucleotides, poly(dA-dT)·poly(dA-dT), poly(dA)·

Spectroscopic characterization of pyrene-cyanine dipeptides and their interactions with double-stranded polynucleotides [PDF]

, 2019
Pireni i cijanini poznate su fluorescentne probe. Pireni se često koriste za praćenje konformacijskih promjena proteina kovalentno vezanih na njih dok se cijanini, intrinzično nefluorescentni, odlikuju izrazitom fluorescencijom prilikom vezanja na ...

Vibrational Raman optical activity of polynucleotides

, 1996
Vibrational Raman optical activity (ROA) is measured in our laboratory as a small intensity difference in Raman scattered light from chiral molecules in right and left circularly polarized incident light.[l, 2] Recently, a series of instrumental advances
