Loop-mediated amplification (LAMP) amplifies specific nucleotide sequences but unlike PCR, it runs at a single temperature and positive reactions can be visualized with the naked eye so fragile instrumentation is not required. We have developed a one step, single-tube, accelerated, FMDVspecific RT-LAMP assay for the rapid detection of all seven serotypes of the virus, using primers designed aga...

BACKGROUND The real-time polymerase chain reaction is currently the method of choice for quantifying nucleic acids in different DNA based quantification applications. It is widely used also for detecting and quantifying genetically modified components in food and feed, predominantly employing TaqMan and SYBR Green real-time PCR chemistries. In our study four alternative chemistries: Lux, Plexor...

We have developed a real-time quantitative PCR assay to measure the concentration of DNA extracted in forensic biological traces. Its rapid and sensitive results were obtained in less than 4 hours. This real-time quantification can be performed on the ABI Prism 7700 Sequence Detector using the fluorogenic probe in a TaqMan assay. We suggest a protocol that will be able to detect and quantitate ...

We have developed a one-tube reverse transcription (RT)-PCR method using the real-time TaqMan PCR system for the detection of norovirus genogroup I (NV GGI). By introduction of a novel probe based on locked nucleic acid technology, we enhanced the sensitivity of the assay compared to those of conventional TaqMan probes. The sensitivity of the NV GGI RT-PCR was determined by probit analysis with...

Oral and middle ear infections are biofilm related infections. Fusobacterium nucleatum is considered to be a key species in dental biofilm formation. The aim of this study was to compare conventional and real-time PCR, for the detection of F. nucleatum in saliva, nasopharyngeal secretion and middle ear effusion samples. Sixty samples were collected from 20 patients with otitis media with effusi...

A set of universal oligonucleotide primers specific for the conserved regions of the eubacterial 16S rRNA gene was designed for use with the real-time PCR Applied Biosystems 7700 (TaqMan) system. During the development of this PCR, problems were noted with the use of this gene as an amplification target. Contamination of reagents with bacterial DNA was a major problem exacerbated by the highly ...
