Atomic scissors: a new method of tracking the 5-bromo-2'-deoxyuridine-labeled DNA in situ. [PDF]

PLoS ONE, 2012
A new method of the light microscopy detection of BrdU-labeled DNA in situ is described. It is based on the oxidative attack at the deoxyribose moiety by copper(I) in the presence of oxygen, which leads to the abstraction of hydrogen atom from ...

Base composition of DNA in adenovirus-12-induced tumor [PDF]

, 1969
A series of experiments was conducted to study the base composition of DNA in AVl2-induced tumor and host cells by paper chromatography, and it was found that DNA per cent. guanine-cystosine contents were around 42 % in both of them. The base composition

Microgels and apparatus for PAGE of nucleic acids in one or two dimensions

BioTechniques, 2018
We describe a system for horizontal 1D or 2D PAGE comprising an apparatus and microgels. There is no buffer outside the gel, making handling and sample loading easy.

Probing structural heterogeneities and fluctuations of nucleic acids and denatured proteins [PDF]

Proceedings of the National Academy of Sciences, 2005
We study protein and nucleic acid structure and dynamics using single-molecule FRET and alternating-laser excitation. Freely diffusing molecules are sorted into subpopulations based on single-molecule signals detected within 100 μs to 1 ms.

DNA Renaturation at the Water-Phenol Interface [PDF]

, 2003
We study DNA adsorption and renaturation in a water-phenol two-phase system, with or without shaking. In very dilute solutions, single-stranded DNA is adsorbed at the interface in a salt-dependent manner.

C5-Azobenzene-substituted 2'-Deoxyuridine-containing Oligodeoxynucleotides for Photo-Switching Hybridization

Molecules, 2014
A new photoisomeric nucleoside dUAz bearing an azobenzene group at the C5-position of 2'-deoxyuridine was designed and synthesized. Photoisomerization of dUAz in oligodeoxynucleotides can be achieved rapidly and selectively with 365 nm (forward) and 450
