Mixtures Analysis of Complex Mixtures
Michael Bernstein; Carlos Cobas; Santi Domínguez; Manuel Pérez; Agustín Barba

We describe an NMR method to quantify mixture components in wine, edible oils, etc. The method is fully customizable, and amenable to high throughput operation.

A Complete Wine Analysis Using Multiplets Detection
Dr Michael Bernstein1; Agustín Barba1; Dr Susanne Klein2; Dr Andrea Dreiseitel2; Daniel Heidger2 and Volker Heidger2

NMR mixtures analysis can be used to determine the concentration of key components in wine. Here we show the analysis using SMA from Mestrelab.

Novel Gpr39 Agonists: Correlation Of Binding Affinity Using Label-Free Back-Scattering Interferometry With Potency In Functional Assays
Daniel Brown (1), Niklas Larsson (2), Ola Fjellström (3), Anders Johansson (3), Sara Lundqvist (2), Johan Brengdahl (2), and Richard J. Isaacs (1)

We describe the application of back-scattering interferometry (BSI) to the characterization of small molecule ligand binding to human GPR39 (a GPCR targeted for type-2 diabetes therapy) overexpressed in crude membrane fractions in free solution, including how BSI-derived affinity and functional assay-derived potency correlate for compounds of varying scaffolds

MAB Discovery Technology: A Smart Way to Highly Diverse and Functional Therapeutic Antibodies
Hans-Willi Krell

MAB Discovery GmbH developped a highly integrated process which provides diverse antibodies by starting with a high number of B cells and filtering the relevant antibodies by an early-on functional screening.

PRESEPSIN, A SOLUBLE CD14-SUBTYPE, A POSSIBLE NEW BIOMARKER INCREASES IN SEPTIC PATIENTS’ PLASMA FROM PEDIATRIC DEPARTMENT.
Hayato YAMAGUCHI1), Satoshi KIMURA1), Seiji FUKUOKA1), Emiko NAKAMA1), Hideyasu OTO2), Makoto INOUE2), Takashi SOGA2), Shigetaka KITAZAWA2), Yoh UMEDA2)

Increased plasma concentration of soluble CD14-subtype (presepsin) was observed in pediatric patients with bacteremia. Presepsin could be a possible biomarker of sepsis in pediatric patients, however, their reference interval in children could be lower than that of adults. More studies with larger number of samples are required to confirm the result.

A Novel Approach Toward Microfluidic Drug Metabolite Synthesis – Electrosynthetic Methodology Simulating Cytochrome (CYP450) Oxidation
Romain Stalder, Gregory P. Roth and Philip Podmore

A novel microfluidic technology and electrochemical synthesis method is demonstrated for the efficient generation of known drug metabolites. These metabolites are typically generated on first pass hepatic oxidation in vivo. The FLUX Module, a new microfluidic electrochemical cell manufactured by Syrris Ltd., has been employed to generate the metabolites of five commercial drugs: Tolbutamide, Chlorpromazine, Diclofenac, Primidone and Albendazole.

A complete workflow from sample preparation to analysis using SureSelect target enrichment system for Ion Proton semiconductor sequencing
Christian Le Cocq, Kyeong Soo Jeong, Arjun Vadapalli, Joseph Ong, Elin Agne, Filip Karlsson, Ashutosh Ashutosh, Francisco Useche, Jayati Ghosh, Henrik Johansson, Scott Happe, Douglas Roberts, and Holly Hogrefe

Agilent’s SureSelect Target Enrichment for the Ion Proton Platform provides a comprehensive, efficient, robust, and cost-effective means to sequence subsets of the human genome.

Mutation Induction in Sucrose Synthase 1 to Study Cold Acclimation in Winter Wheat
Rita Armoniene, Gintaras Brazauskas

Sucrose synthase (Ss) catalyzes the reversible conversion of sucrose and a nucleoside diphosphate into the corresponding nucleoside diphosphate-glucose and fructose being one of the main enzymes of carbohydrate metabolism. The objectives of this study were: to create a TILLING population in winter wheat; to identify new alleles of Ss1 gene; to compare relative expression of Ss1 in leaves and crowns of mutant versus wild type plants during cold acclimation.

Characterization of the prehaustorial resistance against leaf rust (Puccinia triticina f. sp. tritici) in Einkorn (Triticum monococcum) by massive analysis of cDNA ends (MACE)
Albrecht Serfling1,2, Sven Templer1,3, Dragan Perovic1, Frank Ordon1

Triticum monococcum, a valuable source for horizontal resistance against P. triticina was analyzed microscopically and by transcriptional profiling. MACE showed the increased expression of chitinases, kinases, peroxidases and pathogenesis related genes in the first 8 hai. The high number of differentially expressd tags and the knowledge about SNPs facilitates in silico mapping and the development of polymorphic markers which may accelerate the transfer of this prehaustorial resistance
