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.

Digital PCR to Determine the Number of Transcripts from Single Neurons after Patch-clamp Recording
Nóra Faragó1,2, Ágnes K. Kocsis3, Sándor Lovas3, Gábor Molnár3, Márton Rózsa3, Viktor Szemenyei3, Ágnes Zvara2, Gábor Tamás3, László G Puskás1,2

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.

On-chip quantification of miRNA using digital droplet PCR
Q. Cai1, R.S. Wiederkehr1, B. Jones1, B. Majeed1, T. Stakenborg1, P. Fiorini1, L. Lagae1, M Tsukuda2, T. Matsuno2, I. Yamashita2

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.

RNA Quality Control using the Agilent 2200 TapeStation System –Assessment of the RINe Quality Metric
Arunkumar Padmanaban, Ruediger Salowsky, Charmian Cher

Here, we present a comparative study between the RINe quality score obtained from R6K ScreenTape and High Sensitivity R6K ScreenTape compared to the RIN quality metric obtained from the 2100 Bioanalyzer system.
