Unlocked nucleic acid (UNA) and UNA derivatives: Thermal denaturation studies [PDF]
A study on the thermal stability of duplexes formed between unlocked nucleic acid (UNA) modified DNA and RNA oligonucleotides and complementary DNA and RNA is presented. The acyclic UNA monomers are shown to induce a decrease in duplex thermal stability.

Cytofluorometric studies on conformation of nucleic acids in situ. II. Denaturation of deoxyribonucleic acid. [PDF]
Thermal denaturation of deoxyribonucleic acid (DNA) in situ in individual unbroken cells is studied by a cytofluorometric method. This method allows us to investigate DNA denaturation in the presence of divalent cations at concentrations reported to be necessary to maintain native structure of nuclear chromatin.

Synthesis and Evaluation of Artificial Nucleic Acid Bearing an Oxanorbornane Scaffold
Natural oligonucleotides have many rotatable single bonds, and thus their structures are inherently flexible. Structural flexibility leads to an entropic loss when unwound oligonucleotides form a duplex with single-stranded DNA or RNA.

Fabrication of Silver Nanoparticles Against Fungal Pathogens
The use of silver nanoparticles (AgNPs) against various pathogens is now being well recognized in the agriculture and health sector. Nanoparticles have been shown to exhibit various novel properties and these properties, on other hand, rely upon the size,

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

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

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