The novel quantitative technique of "Targeted Profiling" of 1H 1D NMR data is applied to a unique model of rheumatoid arthritis. A number of candidate biomarkers not previously identified using NMR techniques are identified related to inflammation and immune response. The pharmaceutical relevance of several of these metabolites is discussed.

At present, metabolite profiling is of growing importance in herbal medicine fields such as breeding, formulation, quality control and clinical trials. Herbal metabolic profiling allows direct detection of down-stream derivatives of metabolites, arising from herbal formulation process, using metabolite profiling ultra performance liquid chromatography time-of-flight mass spectrometry.

Metabolic profiling is concerned with the analysis of low molecular weight compounds present in complex samples such as plasma. Analytical techniques such as UPLC/MS are proving to be powerful tools for metabolic profiling on complex samples such as plasma. Here we describe a protocol of metabolic profiling analysis on plasma by UPLC/MS.

Following the identification of a lead compound, the usual next step is optimization of that lead via slight structural modifications to improve or retain potency while simultaneously minimizing liabilities. Achieving this balance of required properties is a significant challenge. ACD/Structure Design Suite is a software tool that significantly helps the medicinal compounds that are expected to produce analogs with improved selected physicochemical properties.

We study the optical response of a SPRi detection system, characterizing temperature, stringency and time dependence of molecular interactions for the development of a DNA biochip. We are adapting this system and improve its robustness developing applications, as a 900 spots microarray identifying 65 mutations of the cystic fibrosis, for medical uses and industrial commercialization.

The work presented in this poster covers the investigation of key parameters for the expansion of stem cells in an automated micro-well format. The effect of inoculation seeding density (ICD), well size, passage number and feeding strategies on the proliferation of human mesenchymal stromal cells (hMSC) was investigated. In parallel the effect of well size and seeding density on the proliferation of mouse embryonic stem (mES) cells was also examined.

The Genarrayt 200+ Foods IgG test comprises of glass slides onto which 16 microarrays of over 200 different foods have been printed. Each microarray includes standards for quantitation and positive and negative controls for quality control. Food IgGs are detected by a novel fluorescent dye labelled anti-human IgG conjugate and results are measured using a laser scanner. Fluorescence intensity is directly proportional to antibody activity in the sample.

UV absorption as a technique to detect and quantify biomolecules is routine in molecular biology. LFII™ is a quantum leap up from this state to one that allows the effective imaging of separating biomolecules in an electrophoretic system. The current Peregrine system is based on standard capillary electrophoresis (CE) of biomolecules such as DNA and proteins, small molecules and larger entities such as bacteria and viruses.

High throughput screening (HTS) is an expensive part of the drug development process. Increasing the efficiency and productivity of HTS is a key objective for today’s discovery organizations. Predictive technology can be used to direct the screening of compounds prior to synthesis. However, issues such as the small proportion (usually less than 1%) of hits that occur in a given assay, complicate the application of statistical analysis and predictive modeling to this data.

The quest for solving protein structure largely relies upon X-Ray diffraction, a method requiring crystalline forms of the target protein. Among the many steps comprising structure determination, the process of protein crystallization represents one of the most significant, time-consuming challenges. A new low sample volume, automated dynamic light scattering (DLS) technology has been developed – the DynaPro Plate Reader.
