Book Description
This detailed volume covers conventional MS-based “shotgun lipidomics” by which samples are introduced by infusion or loop injection, as well as LC-MS-based lipidomics, which are becoming increasingly important due to the ever-increasing demand for a complete and precise lipid analysis of the complex and diversified lipids in nature. The volume features protocols applying chemical reactions, the on-line photochemical reactions combined with various MS methods for comprehensive characterization of various lipid classes, and quantification of specific and rare lipids. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Mass Spectrometry-Based Lipidomics: Methods and Protocols serves as an invaluable guide for biochemists and mass spectroscopists who are interested in lipid studies.

Book Description
This authoritative book on MALDI MS, now finally available in its second edition and edited by one of its inventors, gives an in-depth description of the many different applications, along with a detailed discussion of the technology itself. Thoroughly updated and expanded, with contributions from key players in the field, this unique book provides a comprehensive overview of MALDI MS along with its possibilities and limitations. The initial chapters deal with the technology and the instrumental setup, followed by chapters on the use of MALDI MS in protein research (including proteomics), genomics, glycomics and lipidomics. The option of MALDI-MS for the analysis of polymers and small molecules are also covered in separate chapters, while new to this edition is a section devoted to the interplay of MALDI MS and bioinformatics. A much-needed practical and educational asset for individuals, academic institutions and companies in the field of bioanalytics.

Book Description
Imaging mass spectrometry (MS) analysis allows scientists the ability to obtain spatial and chemical information of analytes on a wide variety of surfaces. The ability to image biological analytes is an important tool in many areas of life science research, including: the ability to map pharmaceutical drugs in targeted tissue, to spatially determine the expression profile of specific proteins in healthy vs. diseased tissue states, and to rapidly interrogate biomolecular microarrays. However, there are several avenues for improving the imaging MS experiment for biological samples. Three significant directions this work addresses include: (1) reducing chemical noise and increasing analyte identification by developing sample preparation methodologies, (2) improving the analytical figures of merit (i.e., spatial resolution, analysis time) by implementing a spatially dynamic optical system, and (3) increasing both mass spectral resolution and ion detection sensitivity by modifying a commercial time-of-flight (TOF) MS. Firstly, sample methodology schemes presented in these studies consist of obtaining both?top-down? and?bottom-up? information. In that, both intact mass and peptide mass fingerprinting data can be obtained to increase protein identification. This sample methodology was optimized on protein microarrays in preparation for bio tissue analysis. Other work consists of optimizing novel sample preparation strategies for hydrated solid-supported lipid bilayer studies. Sample methods incorporating nanomaterials for laser desorption/ionization illustrate the ability to perform selective ionization of specific analytes. Specifically, our results suggest that silver nanoparticles facilitate the selective ionization of olefin containing species (e.g., steroids, vitamins). Secondly, an advanced optical design incorporating a spatially dynamic optical scheme allows for laser beam expansion, homogenization, collimation, shaping, and imaging. This spatially dynamic optical system allows user defined beam shapes, decreases analysis times associated with mechanical movement of the sample stage, and is capable of increasing the MS limits of detection by simultaneously irradiating multiple spots. Lastly, new data acquisition strategies (multiple anode detection schemes) were incorporated into a commercial time-of-flight mass spectrometer to increase both sensitivity and resolution in a matrix assisted laser desorption/ionization mass spectrometer. The utility of this technique can be applied to many different samples, where high mass spectral resolution allows for increased mass measurement accuracy.

Book Description
Chemical derivatisation of functional groups has proved popular since the beginning of organic mass spectrometry as a means to enhance the stability and volatility of the analytes as well as facilitating structure elucidation. This book provides comprehensive information on the wide range of derivatisation methods. Each chapter looks at a particular area of derivatisation and includes extensive references to the literature for further research where necessary. There are nearly 1800 references, which, as well as full bibliographic information, include chapter/paper titles where appropriate and Digital Object Identifiers (DOIs) to allow easy retrieval of the online version of the referenced publication. The emergence of atmospheric pressure ionisation and other soft ionisation techniques has not diminished the interest in such chemical techniques, as witnessed by the many chemical tags used in quantitative proteomics (Chapter 9). The last two chapters, a substantial part of the book, deal with derivatisation for use with soft ionisation of both small and large molecules. Chapters Silylation Acylation Alkylation (Arylation) Cyclic derivatives Monofunctional compounds Polyfunctional compounds On-line derivatisation/degradation Soft ionisation—small molecules Soft ionisation—large molecules
