Effects of Superparamagnetic Nanoparticle Clusters on the Polymerase Chain Reaction

open access: yesApplied Sciences, 2012
The polymerase chain reaction (PCR) method is widely used for the reproduction and amplification of specific DNA segments, and a novel PCR method using nanomaterials such as gold nanoparticles has recently been reported. This paper reports on the effects

Application of PCR-DGGE in determining food origin : cases studies of fish and fruits [PDF]

open access: yes, 2008
The determination of geographical origin is a demand of the traceability system of import-export food products. For this purpose, molecular techniques employing 16S, 26S rDNA profiles generated by PCR-DGGE (polymerase chain reaction - denaturing gradient

Genetic diversity among viruses associated with sugarcane mosaic disease in Tucumán, Argentina [PDF]

open access: yes, 2009
Sugarcane leaves with mosaic symptoms were collected in 2006--07 in Tucumán (Argentina) and analyzed by reverse-transcriptase polymerase chain reaction (RT-PCR) restriction fragment length polymorphism (RFLP) and sequencing of a fragment of the Sugarcane

PCR-RFLP Using BseDI Enzyme for Pork Authentication in Sausage and Nugget Products [PDF]

open access: yes, 2011
A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using BseDI restriction enzyme had been applied for identifying the presence of pork in processed meat (beef sausage and chicken nugget) including before and after frying ...

Labeling of Unique Sequences in Double-Stranded DNA at Sites of Vicinal Nicks Generated by Nicking Endonucleases [PDF]

open access: yes, 2008
We describe a new approach for labeling of unique sequences within dsDNA under nondenaturing conditions. The method is based on the site-specific formation of vicinal nicks, which are created by nicking endonucleases (NEases) at specified DNA sites on ...

Thermodynamic and Structural Origins for the Thermostability of Taq DNA Polymerase

open access: yesThe FASEB Journal, 2009
The thermal stability of Taq DNA polymerase is well known, and is the basis for its use in PCR. We have previously shown that at 25oC, Klentaq polymerase (the large fragment domain of Taq) has a folding free energy (δGfold) of ‐27 kcal/mole, making it one of the most stable monomeric proteins yet characterized.

Contribution of Taq polymerase-induced errors to the estimation of RNA virus diversity.

open access: yesJournal of General Virology, 1998
The genetic diversity of a vesicular stomatitis virus population was analysed by RT-PCR, cloning and sequencing of two approximately 500 nucleotide regions of the virus genome.

Clamping-mediated incorporation of single-stranded DNA with concomitant DNA synthesis by Taq polymerase involves nick-translation

open access: yesScientific Reports
The development and characterization of a new enzyme reaction contribute to advancements in modern biotechnology. Here, we report a novel CIS (clamping-mediated incorporation of single-stranded DNA with concomitant DNA synthesis) reaction catalyzed by ...

DGR mutagenic transposition occurs via hypermutagenic reverse transcription primed by nicked template RNA. [PDF]

open access: yes, 2017
Diversity-generating retroelements (DGRs) are molecular evolution machines that facilitate microbial adaptation to environmental changes. Hypervariation occurs via a mutagenic retrotransposition process from a template repeat (TR) to a variable repeat ...

Development of a nucleic acid lateral flow immunoassay for simultaneous detection of Listeria spp. and Listeriamonocytogenes in food [PDF]

open access: yes, 2009
We present a new nucleic acid lateral flow immunoassay (NALFIA) for the assessment of listeria contamination. The detection procedure starts with enrichment of sample in Half Fraser broth (24 h). Following isolation of DNA, a duplex PCR is performed with
