|Detection in Environmental Samples of Enteroagregative Escherichia coli, stx-producing Escherichia coli and stx-converting Bacteriophage by RT- PCR: Preliminary Data|
Mura Elia, Noli Alessia Caterina, Rossi Maria Lucia, Terrosu Giovanni, Fadda Antonio
The aim of this work was to collect epidemiological information concerning the presence of Enteroaggregative Escherichia coli, stx-producing Escherichia coli and stx2a-converting bacteriophage, in ruminants faeces.
|Effect of exposure to stress conditions on propidium monoazide (PMA) - qPCR based enumeration of Campylobacter in broiler carcass rinses|
A. Duarte1,2*, N. Botteldoorn2 ,W. Coucke2, S. Denayer2, K. Dierick2, and M. Uyttendaele1
Evaluation and comparison of a developed PMA-qPCR Campylobacter enumeration method with the reference method, after exposure of the broiler rinse artificially contaminated with the bacteria to stress conditions.
|Quantitative Real-time PCR differentiation between Genetically Modified pollen and Genetically Modified flour in honey|
Eugénia de Andrade1*, Maria Lopes2, Maria Clara Fernandes1, Fátima Quedas2, Isabel Rodrigues1, Amélia Maria Lopes1
We investigated the ability of quantitative real-time PCR, using plasmids calibrants, together with the triploid maize seed endosperm and the haploid pollen, to get good estimates for the copy number of a transgene in relation to the copy number of a species specific gene as a mean to distinguish between pollen and flour from maize.

Whole-cell patch-clamp recording enables detecting electrophysiological signals from neurons, and RNA can be harvested into the patch pipette from the cells.We have optimized a dPCR protocol for determining exact transcript numbers in single neurons after patch-clamp recording by using dPCR based on high-density nanocapillary PCR.

miRNAs have a great potential in diagnostics. Hence, automated profiling of miRNAs are of great interest. In-house technology show that it is possible to implement a multiplexing assay for miRNAs on a microfluidic chip using digital droplet PCR.
|A multianalyte algorithm PCR-based blood test outperforms single analyte ELISA-based blood tests for neuroendocrine tumor detection|
Mark Kidd, Irvin M Modlin, Daniele Alaimo, Stephen Callahan, Nancy Teixiera, Lisa Bodei, Ignat Drozdov
In a prospective study, in age-/sex- and ethnicity-matched patients and controls (n=82), a 51 panel multigene blood transcript test (NETest) was identified to be significantly more sensitive and accurate (>93%) than any single analyte assay (Chromogranin A, Pancreastatin or Neurokinin A) for neuroendocrine tumor detection.
|Stealth-Adapted Viruses and Viteria: Insights into Virus Construction, Replication and Potential Therapies|
W. John Martin
There is an increasing incidence of diseases with accompanying signs and symptoms of brain damage. These include neurological and psychiatric illnesses, childhood behavioral disorders, and such common conditions as chronic fatigue, Gulf War Syndrome, so-called “chronic Lyme disease”, and many cancers. Altogether, these diseases have an enormous social impact.
|High-Throughput Analysis of DNA Samples using the D1K ScreenTape Assay and the Agilent 2200 TapeStation System|
Arunkumar Padmanaban, Ruediger Salowsky, Adam Inche
Recent advances in genomics demands to look at a wealth of genetic information in a short period of time. DNA analysis using slab gel electrophoresis and capillary electrophoresis are widely being used as a QC step in next generation sequencing and microarray studies. However, often these techniques lack the speed and involve more manual steps to perform the assay.
|Hot Start dNTPs – Pushing the Limits of PCR|
Tony Le, Hidalgo Ashrafi, Sabrina Shore, Victor Timoshchuk, Natasha Paul, Richard Hogrefe, Inna Koukhareva, Alexandre Lebedev
Hot Start dNTPs are a distinct approach that employs modified nucleoside triphosphates with a thermolabile protecting group. This modification blocks low temperature primer extension and is released at higher temperatures to allow for more specific DNA polymerase incorporation.
