Journal ArticleDOI
Rapid spontaneous accessibility of nucleosomal DNA.
TL;DR: These results explain how remodeling factors can be recruited to particular nucleosomes on a biologically relevant timescale, and imply that the major impediment to entry of RNA polymerase into a nucleosome is rewrapping of nucleosomal DNA, not unwrapping.
Journal ArticleDOI
Cyanine dyes in biophysical research: the photophysics of polymethine fluorescent dyes in biomolecular environments
Marcia Levitus,Suman Ranjit +1 more
TL;DR: This work has shown that the triplet state is a key intermediate in the photochemical reactions that limit the photostability of cyanine dyes, and a combination of oxidizing and reducing agents is the most efficient way of guaranteeing that the ground state is recovered rapidly and efficiently.
Journal ArticleDOI
Steps To Demarcate the Effects of Chromophore Aggregation and Planarization in Poly(phenyleneethynylene)s. 1. Rotationally Interrupted Conjugation in the Excited States of 1,4-Bis(phenylethynyl)benzene
Marcia Levitus,Kelli Schmieder,Holly L. Ricks,Ken D. Shimizu,Uwe H. F. Bunz,Miguel A. Garcia-Garibay +5 more
TL;DR: A series of photophysical measurements and semiempirical calculations were carried out with 1,4-bis(phenylethynyl)benzene in search of evidence on the effects of phenyl group rotation and chromophore aggregation of oligo- and poly(phenyleneethynylene)s.
Journal ArticleDOI

TL;DR: A multi-laboratory study finds that single-molecule FRET is a reproducible and reliable approach for determining accurate distances in dye-labeled DNA duplexes.
Journal ArticleDOI
Fluorescence Properties and Photophysics of the Sulfoindocyanine Cy3 Linked Covalently to DNA
TL;DR: The remarkable variations in the photophysical properties of Cy3-DNA constructs demonstrate that caution should be used when Cy3 is used in studies employing DNA conjugates, and it is observed that the activation energy for photoisomerization depends strongly on the microenvironment in which the dye is located.
