Peptide sequencing by surface-induced dissociation (SID) on a MALDI-Ion Mobility-orthogonal-TOF mass spectrometer is demonstrated. The early version of the instrument used for proof-of-concept experiments achieves a mobility resolution of approximately 20 and TOF mass resolution better than 200. Peptide sequences of four peptides from a tryptic digest of cytochrome c (ca. 1 pmol deposited) were obtained. The advantage of IM-SID-o-TOFMS is that a single experiment can be used to simultaneously measure the molecular weights of the tryptic peptide fragments (peptide mass mapping) and partial sequence analysis, (real time tandem mass spectrometry.) Optimization of the MALDI-IM-SID-o-TOF mass spectrometer for peptide sequencing is discussed. SID spectra obtained by using stainless steel, Au grids, and fluorinated self-assembled monolayers (F-SAM) on Au are compared. Optimum collision energies differ for the various surfaces. The fragmentation patterns observed for a series of peptides and protein digests using the Nd:YAG laser (355 nm) for MALDI ion formation and an FSAM surface for ion activation is compared to the fragmentation patterns observed for CID and photodissociation. The fragmentation patterns observed in all cases are strikingly similar. Photodissociation produced a greater abundance of ions resulting from side-chain cleavages. As a general rule optimized SID spectra contain fewer immonium ions than either photodissociation or CID. Evaluation of an instrument incorporating a new hybrid drift cell is discussed. Spectra for a digest of hemoglobin is compared to that acquired with an ABI 4700 TOF-TOF. The performance of the instrument is also evaluated using a micro-crystal Nd:YAG laser (355 nm) for MALDI operated at 400 Hz. Experiments were performed to determine the sensitivity and overall performance of the instrument. The reproducibility of the MS/MS spectra for gramicidin S is shown to be 94% run-to-run. The best mobility resolution obtained for a neat deposition of the dye Crystal Violet was 60 t/[delta]t. Sensitivity was tested with the peptide fibrinopeptide A (m/z 1537, AA sequence ADSGEGDFLAEGGGVR). Data acquired for sixty seconds with approximately sixty femtomoles deposited. Abundant [M+H]+ ions where observed as well as [M+H]+-NH3 ions. The S/N for this short run was insufficient to identify any SID fragments.

Discover how advances in mass spectrometry are fueling new discoveries across a broad range of research areas Electrospray and MALDI Mass Spectrometry brings both veteran practitioners and beginning scientists up to date with the most recent trends and findings in electrospray ionization and matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. In particular, this Second Edition highlights how advances in electrospray and MALDI mass spectrometry are supporting important discoveries in new and emerging fields such as proteomics and metabolomics as well as in traditional areas of chemistry and physics research. Electrospray AND MALDI Mass Spectrometry, SECOND EDITION is divided into five parts: Part A, Fundamentals of ES, explains the fundamental phenomena underlying the electrospray process, including selectivity in ionization and inherent electrochemistry, and concludes with a chapter offering a comparative inventory of source hardware Part B, Fundamentals of MALDI, confronts ionization mechanisms, instrument development, and matrix selection, and includes a final chapter that explores the special application of MALDI to obtain two-dimensional images of spatial distributions of compounds on surfaces Part C, ES and MALDI Coupling to Mass Spectrometry Instrumentation, examines the coupling of these ionization techniques to various mass analyzers, including quadrupole ion trap, time-of-flight, Fourier transform ion cyclotron resonance, and ion mobility mass spectrometers Part D, Practical Aspects of ES and MALDI, investigates analytical issues including quantification, charge-state distributions, noncovalent interactions in solution that are preserved as gas-phase ions, and various means of ion excitation in preparation for tandem mass spectrometry, and offers a guide to the interpretation of even-electron mass spectra Part E, Biological Applications of ES and MALDI, examines the role of mass spectrometry in such areas as peptide and protein characterization, carbohydrate analysis, lipid analysis, and drug discovery Written by a team of leading experts, the book not only provides a critical review of the literature, but also presents key concepts in tutorial fashion to help readers take full advantage of the latest technological breakthroughs and applications. As a result, Electrospray and MALDI Mass Spectrometry will help researchers fully leverage the power of electrospray and MALDI mass spectrometry. The judicious compartmentalization of chapters, and the pedagogic presentation style throughout, render the book highly suitable for use as a text for graduate-level courses in advanced mass spectrometry.

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

The introduction of the matrix-assisted laser desorption ionization technique (MALDI) changed mass spectrometry (MS) into a powerful tool for biomedical analysis that is now widely employed in academic as well as industrial laboratories. The 2002 Nobel Prize was awarded for the development of methods for identification and structure analyses of biological macromolecules. MALDI is one of the two mass spectrometric methods besides Electrospray which is universally used for this purpose. This unique book gives an in-depth description of the many different applications of MALDI MS, along with a detailed discussion of the technology itself. It will be a much-needed practical and educational asset for individuals, academic institutions and companies in the field of bioanalytics.

This 2014 Article IV Consultation highlights that Maldives’ real economy has picked up. Growth is estimated to have reached 5 percent in 2014 with stronger tourism activity driven by a rapid expansion from Asian markets and a tepid recovery from Europe. The IMF staff expects growth to be about 5 percent in 2015. Weaker import prices have pushed down inflation to low levels. Growth is expected to remain relatively strong in the near term, though the fiscal adjustment envisaged in the 2015 Budget will have a mildly negative effect on growth.
