|Exploring the Therapeutic Potential of a Peptide Derived from a Poxviral Immune Evasion Protein|
•9R-VIPER is an effective at TLR4 and TLR2 signal inhibition than VIPER.
•The structure of 9R-VIPER and the mutant peptide L6AE10A were investigated by NMR.
•Important structural information was uncovered and an explanation was found for the loss
of activity when important residues are changed.
|MS Data Processing With Full Flexibility Of Universal Processing Software|
Frans Schoutsen, Barbara van Cann, Vincent Jespers, Michal Godula
Liquid Chromatography (LC) in combination with triple quadrupole Mass Spectrometry (MS) is more and more a common analysis technique in routine laboratories. Especially when using MS/MS selected reaction monitoring (SRM) for a large number of components data handling can be a bottle neck. This poster will show MS data processing of pesticides in water samples using an already established chromatography data system which is now also capable of processing large quantities of MS data.
|Analysis of Dithiocarbamate Pesticides by GC-MS|
Soma Dasgupta1,2, Sumaiyya Mujawar1, Kaushik Banerjee1, Hans-Joachim Huebschmann3, Paul Silcock4
Analysis of dithiocarbamate pesticides (DTCs) using an optimized GC-MS method is described. DTCs are not stable and cannot be extracted or analyzed directly. The purpose of this work was develop a reliable method for identification and quantification of residues.
|Analysis of Multiresidue Pesticides Present in Ayurvedic Churna by GC-MS/MS|
Manoj Surwade, Sunil T Kumar, Aarti Karkhanis, Manish Kumar, Soma Dasgupta, Hans-Joachim Huebschmann, Paul Silcock, Thermo Fisher Scientific
Analysis of Herbal powders or ‘churnas’ using an optimized GC-MS/MS method is described. As they have high amount of matrix co-extractives, they pose critical analytical problems. The purpose of this work was overcome the effect of the matrix and develop a reliable method.
|Automated Solid-Phase Extraction of Oraganochlorine Pesticides from Drinking Water|
Frans Schoustsen and Pranathi R Perati
A new method was developed to automate the capture and elution of Organochlorine pesticides from drinking water. The concentrated analytes were then analyzed by GC with Electron Capture Detection (ECD).
|GC-MS/MS Analysis of Pesticide Residue in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent|
Cojocariu C., Morgan P., Silcock P., Godula M
QuEChERS involves an initial step when a few grams of the sample are extracted with acetonitrile followed by a clean-up step (with dispersive-SPE) used to remove, to a certain extent, unwanted matrix compound (such as pigments, sugars, organic acids). With QuEChERS, the final extract ends up with the pesticides in acetonitrile, which, being polar solvent, can be
problematic in GC-MS.
|Increasing Extraction Efficiency of Pesticides and Dioxins from Wet Samples Using a Novel Polymer During Accelerated Solvent Extraction|
Katerina Bousova, Pranathi Perati, Rahmat Ullah, Kannan Srinivasan
Thermo Scientific™ Dionex™ ASE™ Prep MAP is a proprietary polymer designed to remove moisture and increase extraction efficiencies from wet samples including soils, tissues and food products. This unique formulation allows moisture removal under a variety of ionic strength conditions and accelerated solvent extraction conditions.
|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.
