Sequence-Specific Interactions of Methylene Blue with Polynucleotides and DNA: A Spectroscopic Study

, 1994
The modes of binding of the phenothiazinium dye methylene blue (1) to alternating and nonalternating polynucleotides and to calf thymus (CT) DNA have been characterized using linear dichroism (LD) and circular dichroism (CD) spectroscopy.

Na+ effects on transitions of DNA and polynucleotides of variable linear charge density

Biopolymers, 1976
A range of linear charge densities of the ordered and disordered forms of DNA or polynucleotides can be obtained experimentally by acid or alkaline titration, or by the investigation of unusual complexes involving protonated bases or three‐stranded ...

Stereochemistry of nucleic acids and their constituents. X. solid‐slate base‐slacking patterns in nucleic acid constituents and polynucleotides

Biopolymers, 1971
The base‐stacking patterns in over 70 published crystal structures of nucleic acid constituents and polynucleotides were examined. Several recurring stacking patterns were found.

32P-postlabeling analysis of IQ, MeIQx and PhIP adducts formed in vitro in DNA and polynucleotides and found in vivo in hepatic DNA from IQ-, MeIQx- and PhIP-treated monkeys.

Carcinogenesis, 1993
The 32P-postlabeling method was used to examine the adducts in DNA, polynucleotides, and mononucleotides reacted in vitro with the N-hydroxy and N-acetoxy derivatives of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), 2-amino-3, 8-dimethylimidazo[4,5-f ...

Circular dichroism of polynucleotides: A simple theory

, 1969
A particularly simple theory of circular dichroism is described and applied to the polynucleotides. It works surprisingly well and predicts the conservative spectrum of DNA and the more intense nonconservative spectrum of RNA.

Characterization of the binding of YO to [poly(dA‐dT)]2 and [poly(dG‐dC)]2, and of the fluorescent properties of YO and YOYO complexed with the polynucleotides and double‐stranded DNA

Biopolymers, 1995
The interaction between the fluorescent dye YO (oxazole yellow) and the alternating polynucleotides [poly(dA‐dT)]2[the duplex of alternating poly(dA‐dT)]and [poly(dG‐dC)]2[the duplex of alternating poly(dG‐dC)] has been studied with optical spectroscopic
