Characterization and Collision Cross Section Determination of Obesity Related Lipids Within Mouse Models Using Travelling Wave IMS-QTOF Mass Spectrometry

Characterization and Collision Cross Section Determination of Obesity Related Lipids Within Mouse Models Using Travelling Wave IMS-QTOF Mass Spectrometry

9 Aug 2015

This poster demonstrates the characterization of the liver cell lipid complement using ion-mobility and associated collision cross section (CCS) databases, obtained with a novel geometry travelling wave IMS-QTOF MS platform, for obese mouse models which have undergone treatment to prevent or reverse obesity. Obesity is a risk factor associated with metabolic syndrome, and can be affected by manipulation of glucosylceramide levels, through treatment with glucosylceramide synthase inhibitors.

Vion IMS QTof

Vion IMS QTof is a high resolution QTof mass spectrometer that delivers the selectivity of ion mobility to every scientist, for every analysis. Does high resolution, accurate mass data always lead to the correct answer first time? Avoid additional confirmatory experiments by utilizing the selectivity of ion mobility. Featuring new geometry and including XS Ion Optics and the QuanTof2 detection system, the Vion IMS QTof  has the sensitivity and dynamic range to make ion mobility quantitative and routinely usable, enabling: Easier data interpretation as ion mobility cleans up and simplifies every spectrum Confident identification and quantification of analytes Faster method development and higher sample throughput Greater selectivity than conventional MS/MS with HDMSE With Vion IMS QTof you can use the selectivity of ion mobility to quickly refine spectra and discount chromatographically co-eluting compounds and background interferences. Enabling you to characterize your compounds with confidence. The ability to gather and process CCS data for every ion gives you more confidence in your data than ever before. Vion IMS QTof is driven by UNIFI scientific information system to deliver the most comprehensive analytical workflow, enabling you to target, identify, and review results in a single software platform. Make more informed decisions, faster. CCS provides chromatographic retention time independent data points, enabling confident identification of your analytes and reducing the risk of false positives and false negatives. Even during initial sample analysis, without any retention time knowledge, you can use theoretical exact mass and CCS library values to identify unknown and unexpected components. Applications: Screening - Meeting legislative and regulatory demands requires the utmost confidence in your data. UNIFI informatics workflows integrate the value of CCS, reducing false positives and false negatives driving laboratory efficiency. Pharma - The combination of UNIFI and Vion IMS QTof brings ion mobility to your drug discovery experiments while maintaing ease and efficiency you need for your routine Met ID processes. Omics - A recurring challenge for omics studies is the identification and structural elucidation of metabolites, lipids, and peptides of interest. Incorporating Vion IMS QTof into your workflow gives you not only CSS data from every component, but also increase analytical space and resolution.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

The research is conducted inside universities, medical schools, pharmaceutical companies, farms, defence establishments, and commercial facilities that provide animal-testing services to industry. It includes pure research such as genetics, developmental biology, behavioral studies, as well as applied research such as pharmaceutical testing in pre-clinical, before human, studies. MetabolomicsMetabolomics is the study of small metabolites (the intermediates and products of metabolism). It involves the identification and quantification of cellular metabolites using analytical technologies such as GC, HPLC, NMR, and LC/MS.InhibitorsLipidomics
