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

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

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

Precision and accuracy of single-molecule FRET measurements—a multi-laboratory benchmark study

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.
