|Performance Characteristics of a Comprehensive Two=Dimensional Gas Chromatography-High Resolution Time-of=Flight Mass Spectrometry System (GCxGC=HRTOFMS) Utilizing Chemical Ionization|
Jonelle Shiel, Mark Merrick, Scott Pugh, Matthew Soyk, and Viatcheslav Artaev
Combining comprehensive two-dimensional gas chromatography (GC×GC) with a High Resolution Time-of-Flight Mass Spectrometer and Chemical Ionization is a powerful tool for compound identification. Performance of the LECO Pegasus GC-HRT 4D using Chemical Ionization (CI) was demonstrated using Benzophenone and Diesel. GC×GC separation results in narrow peaks, therefore, a high speed detection system is necessary.
|Non-Target Analysis of Electronic Waste Samples from China|
Jonathan D. Byer, Ed Sverko, Kurunthachalam Kannan, Qian Wu, Joe Binkley
GC×GC-HRT is a powerful tool for the comprehensive analysis and
chemical characterization of analytes in complex matrices. The combination of high resolution front-end separation with high
resolution time-of-flight mass spectrometry made possible the
identification of compounds previously unknown in these samples.
|Single Cell Whole Genome Amplification|
The analysis of genomes at the single cell level offers unprecedented biological insights in diverse fields such as cancer research, immunology & microbiology. This poster discusses the a technology for amplification of genomic DNA form a single cell, that provides utmost sensitivity, accuracy & robustness. GE Healthcare Life Sciences had previously developed method of multiple strand displacement amplification (MDA) by Phi29 DNA polymerase
|The Prestwick Chemical Library (R), A Valuable Tool for Screening|
Jean-Marie Contreras1, Christophe Morice1, Jean-Marc Simon1, Bruno Didier2, Marie-Louise Jung1 and Thierry Langer3
The Prestwick Chemical Library® (PCL) is Prestwick’s flagship product dedicated to screening. It is a collection of 1280 molecules comprising 100% approved drugs (FDA, EMEA and other agencies) selected for their high chemical and pharmacological diversity. The PCL was designed to reduce the risk of "low quality" hits and therefore the cost of the initial screening, and appears to be an efficient smart library for hit discovery. The PCL comes with an extended fully-annotated database.
|Spice Wars- Are You Battle Ready? Analysis of Synthetic Cannabinoids via Gas Chromatography—High Resolution Time-of-Flight Mass Spectrometry|
David E. Alonso, John Rorabeck, and Joe Binkley
-EI/CI workflow facilitates confident compound identification.
-GC-HRT and HR-CI source provides high quality, accurate mass data for:
-Database searches (NIST, Wiley, etc.)
-Formula determination (fragment, molecular, and adduct ions)
|System-Specific Periodicity in qPCR Data and its Impact on Quantitation|
Joel Tellinghuisen,1 Stefan Roediger,2 Thomas Volksdorf,3 and Andrej-Nikolai Spiess3
In some commercial qPCR instruments, the fluorescence signal shows reaction-to-reaction periodicity in all cycles, and this translates into periodicity in threshold-based Cq markers.
|Bovine RNA-seq data analysis of liver and pituitary gland|
Pareek CS12, Smoczynski R12, Dziuba P12, Sikora M12, Golebiewski M2, Blaszczyk P12, Gelfand B3, Yaping F3, Kumar D3.
Two key applications of RNA-seq i.e., i) transcriptome read mapping to a reference genome and ii) SNP detections were investigated to analysis of bovine liver and pituitary gland transcriptome. Here, we have presented ONLY the obtained results of bovine pituitary gland.
