Quantitative PCR: the determination of template copy numbers by temperature gradient gel electrophoresis (TGGE) Low copy numbers of DNA or RNA sequences can be quantified easily by combining PCR (Polymerase Chain Reaction) and TGGE (Temperature Gradient Gel Electrophoresis). This combination allows to overcome the problems of quantitive PCR caused by plateau effects, uneven priming or, variable...

The dataset presented in this article is related to the research article entitled "Detection of HER2 Gene Polymorphism in Breast Cancer: PCR Optimization Study" (B.R. Budiarto, Desriani, 2016) [1] with some modification in primers used and in PCR optimization strategy to eliminate false-positive result that may occur in HER2I655V polymorphism detection. Combining a new set of primers with PCR g...

A study was carried out to identify the microbial diversity in wastewater from tuna industry, samples were obtained at different points process, analysis using molecular tools such as metagenomics, Electrophoresis technique Denaturation Gradient Gel (DGGE) and Polymerase Chain Reaction (PCR). The sensitivity of these techniques allowed amplification 16S rDNA gene fragments by means specific pri...

Denaturing gradient gel electrophoresis (DGGE) is based upon the different melting behaviors of DNA molecules in a chemical denaturant gradient according to their sequences. This technique has recently become a widespread tool to detect mutations. The introduction of a GC-clamp enables the detection of most single base differences between two DNA molecules. As a test system we have applied the ...

Denaturing Gradient Gel Electrophoresis is a influential and feasible device for sequence examination of the variety of complicted natural microbial populations. For PCR amplification of 16S rDNA products and specific primers were used and analyzed by denaturing gel electrophoresis in gradient. Probes specific for the cluster Genusand were designed to bind to sequences within the region amplifi...

We present a novel denaturing gradient gel electrophoresis (DGGE) method which characterizes multiclonal communities of Staphylococcus aureus. The spa PCR-based DGGE method simultaneously separates strains that differ in only one base, thereby revealing multiclonal colonization and infections.

Computed tomography revealed a frontal empyema in an 8 month old boy who presented with a prolonged convulsion. Before admission he had received oral antibiotics and all specimens were negative on culture. The presence of bacteria in cerebrospinal and empyema fluid was demonstrated using the polymerase chain reaction (PCR) with 16S rRNA gene primers. A presumptive identification of Streptococcu...
