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.

Computer programs for analysis of nucleic acid hybridization, thermal denaturation, and gel electrophoresis data. [PDF]
Computer programs for the analysis of data from techniques frequently used in nucleic acids research are described. In addition to calculating non-linear, least-squares solutions to equations describing these systems, the programs allow for data editing, normalization, plotting and storage, and are flexible and simple to use.

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.

An improved nucleic acid sequence-based amplification method mediated by T4 gene 32 protein.
The uptake of Nucleic Acid Sequence-Based Amplification (NASBA) for point of care testing may be hindered by a complexity in the workflow due the requirement of a thermal denaturation step to initiate the cyclic isothermal amplification before the ...

Denaturation of proteins and nucleic acids by thermal-gradient electrophoresis [PDF]
A polyacrylamide-gel-electrophoresis method has been developed that permits the analysis of conformational changes that occur during the thermal denaturation of macromolecules. A stable transverse temperature gradient was produced in an aluminium heating jacket clamped around a vertical polyacrylamide slab gel.

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.

Denaturation and condensation of intracellular nucleic acids monitored by fluorescence depolarization of intercalating dyes in individual cells. [PDF]
The intercalating binding of planar aromatic dye molecules to nucleic acids can be analyzed using fluorescence depolarization measurements of the dye molecules excited by linearly polarized light. In this study, we investigated the conformational changes of the intracellular DNA-dye complex in single cells.

Computer programs to assist in high resolution thermal denaturation and circular dichroism studies on nucleic acids [PDF]
Computer programs are described that direct the collection, processing, and graphical display of numerical data obtained from high resolution thermal denaturation (1-3) and circular dichroism (4) studies. Besides these specific applications, the programs may also be useful, either directly or as programming models, in other types of spectrophotometric ...
