Dengue fever is an emerging disease in Pakistan with uninterrupted increase in number of cases since 2006 Dengue fever epidemic in Lahore Pakistan. This study was planed to identify serotypes of dengue virus (DENV) involved in epidemic of 2008. The patients were screened in the microbiology laboratory with immunochromatographic kits then confirmed by antibody capture Enzyme linked immunosorbent...

Introduction. Polymerase chain reaction (PCR)-based diagnostic tests use purifi ed nucleic acids (NAs) from clinical samples. The NAs cation step adds time, cost, and aff ects the quality of testing. objective this study was to develop a protocol for direct saliva in genetic markers, without acids. Methods. PCR, real-time RT-PCR isothermal amplifi were used detection Results. We report markers ...

Pre-amplification is a basis for numerous polymerase chain reaction (PCR) protocols but bears severe contamination risks due to handling of high-copy DNA samples. Therefore we developed a self-contained centrifugal microfluidic system comprising pre-stored reagents; it enables pre-amplification of specific DNA sequences prior to automated aliquoting and real-time PCR in a modified commercial th...

Methods Data from August 2009 to December 2010 were collected. In high-risk patients and those with moderate to severe influenza-like illness (ILI), diagnosis of influenza A and pandemic (H1N1) influenza were confirmed by real-time reverse-transcription polymerase chain reaction (rRT-PCR) by Roche LightCycler 2.0 system. Seven RIDTs were used and results were compared with rRT-PCR to assess per...

In order to facilitate optimal plant DNA quantitation and identification, an assay has been developed that uses generic plant PCR primers that amplify a region in the chloroplast genome of plant samples. The assay uses the SYBR green detection dye to detect the PCR product with a universal PCR primer set to the large subunit of ribulose bisphosphate carboxylase, rbcL, but can be used with any o...

Quantification of mRNAs using real-time polymerase chain reaction (PCR) by monitoring the product formation with the fluorescent dye SYBR Green I is being extensively used in neurosciences, developmental biology, and medical diagnostics. Most PCR data analysis procedures assume that the PCR efficiency for the amplicon of interest is constant or even, in the case of the comparative C(t) method, ...
