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

open access: yes, 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 ...

The Origins of Life: What One Needs to Know

open access: yesZygon, 1997
Many solar systems in the universe may be expected to contain rocky planets that have accreted organic compounds. These compounds are likely to be universally found. In addition, the chemistry of sulfur, phosphorus, and iron is likely to dominate energy

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

open access: yes, 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)·

Sensitive determination of nucleotides and polynucleotides based on the fluorescence quenching of the Tb3+-Tiron complex

open access: yes, 1997
A sensitive method using fluorescence quenching for the determination of nucleotides (ATP, ADP, AMP, CTP, UTP) and polynucleotides [poly(A), poly(I), poly(U)] is proposed.

Electrophoretic mobility shift assay of double-stranded polynucleotides with different chain lengths in the presence of tau protein.

open access: yes, 2013
Double-stranded polynucleotides (100 ng) with different chain lengths (as indicated in each lane and Table 1) were incubated with tau23 at a ratio [protein]/[DNA] of 1/10 in the buffer of 20 mM Tris-HCl (pH 7.2), containing 50 mM NaCl, 0.5 mM DTT, 1 mM ...

Vibrational Raman optical activity of polynucleotides

open access: yes, 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
