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.

Characterization of Protein and Protein Aggregates using Temperature-controlled Hollow-Fiber Flow-FFF
Trevor Havard, Florian Meier, Evelin Moldenhauer, Soheyl Tadjiki, Thorsten Klein

Reproducibilty Improvements in Field Flow Fractionation can be achieved on two frounts.
1. Instrument design and control, the system used in for this poster is does not require flow controllers or switching valves and there for produces the same conditions in every case.

2. Fractionater design, the design of the cartridges used in this poster maintain excellent conditions to maintain constant pressure at the membrane removing unwanted effects of sale relaxation above the membrane s

Innovative technology that enables RNAi in difficult to transfect cells
Christina Yamada, Kathryn Robinson, Allison St. Amand, Zaklina Strezoska, Greg Wardle, Anastasia Khvorova, Devin Leake

Investigations at Dharmacon have led to the development of innovative siRNA molecules that can be delivered into difficult-to-transfect cells without additional lipid reagents, virus, or instruments. This technology, Accell siRNA reagents, enables gene knockdown for functional genomic studies in a wide variety of cell types. In some instances, cells can be continuously dosed with Accell siRNAs to enable target gene knockdown for extended durations.

THe AtSCL26 transcription factor controls cross-talk between GA and N root architecture in Arabidopsis thaliana roots
Beatriz Lagunas, Anthony D. Carter, Dafyd Jenkins and Miriam Gifford

Phenotypic and molecular evidence supports the hypothesis that developmental program enabling nodule formation arose during evolution from a lateral root ‘blueprint’ pre-existing in all higher plants . We reasoned that analyzing Arabidopsis genes orthologous to regulators of nodulation could shed insight on control of lateral root development. This led us to the discovery that an Arabidopsis GRAS family transcription factor controls lateral root development under specific nitrogen conditions.

LOHA Comprehensive Assay for Single Nucleotide Polymorphism, Copy Number Variants and Loss of Heterozygosity Using SureSelect Target Enrichment
Kyeong Soo Jeong, Arjun Vadapalli, Ashutosh Ashutosh, Paula Costa, Brian Peter, Stephanie Fulmer-Smentek, Magnus Isaksson, Jayati Ghosh, Douglas Roberts, Holly Hogrefe

Here we describe a comprehensive assay that enables researchers to identify SNP, INDEL, CNV, and LOH using SureSelect target enrichment. This design can be employed as a standalone entity or in concert with other bait designs for SNP and INDEL detection. We also describe methods for data analysis and visualization.

Building a Diverse and Experimentally-Curated Fragment Library
Andrew Lowerson, Steven LaPlante, Patrick McCarren, and Michael Serrano-Wu

Presenting a new fragment collection with experimentally-determined aqueous solubility that will address a major source of false positives and attrition in fragment screening

Polymer Microarrays for Biomaterial Development
Simmonte, M.J.1, Dhaliwal, K.2, Cuschieri, K.3, Graham, S.V.4, Bradley, M.1

The application of polymer microarrays in the discovery of biocompatible and bioactive substrates. Progress towards biomaterial development for the treatment of SIRS (systemic inflammatory response syndrome), and improving cervical cytology.

DETERMINATION OF THE QUALITY OF ACTIVE INGREDIENTS IN PAIN KILLERS USING GC-MS
Elizabeth N.M Murago1, Nathan Oyaro1, Anthony N. Gachanja, Onditi O. Anam, Felix M. Mawili, Steve Lancaster

From this study, the pain killers sampled were found to have large error bars suggesting that there exist counterfeit drugs in the market. The brands mostly affected for analysis of acetaminophen were panadol, action, P500, P5500, elymol and neladol. The error bars for caffeine analysis were quite low indicating that all tablets either counterfeit or original maintained the same amount of this active ingredient.
