Imaging mass spectrometry

Abstract: Imaging mass spectrometry combines the chemical specificity and parallel detection of mass spectrometry with microscopic imaging capabilities. The ability to simultaneously obtain images from all analytes detected, from atomic to macromolecular ions, allows the analyst to probe the chemical organization of a sample and to correlate this with physical features. The sensitivity of the ionization step, sample preparation, the spatial resolution, and the speed of the technique are all important parameters that aff… Show more

“…An important component of the success of this technique has been MALDI mass spectrometry imaging (MSI) of tissue sections, which was introduced in 1997 by Caprioli and coworkers [3]. Over the years, MALDI and MSI have emerged as powerful tools for investigating the identity and location of biomolecules in tissue samples and have been extensively employed in biological and in clinical studies [4][5][6][7]. Optimization of both techniques has been conducted with a focus on improving the spatial localization and identification of the detected biomolecules.…”

“…The detector enables proteins up to 70 kDa to be imaged, and proteins up to 110 kDa to be detected, directly from tissue, and indicates new directions by which the mass range amenable to MALDI imaging MS and MALDI profiling MS may be extended. (J Am Soc Mass Spectrom 2010, 21, 1922-1929) © 2010 American Society for Mass Spectrometry S ince its inception Ïł10 y ago, MALDI imaging mass spectrometry (imaging MS) has developed into a powerful and versatile tool for biomedical research [1,2]. It is now routinely used for analyzing peptides and small proteins up to 25 kDa [3-6], administered drugs and their metabolites [7], and recently major improvements have been reported for lipids [8].…”

“…We demonstrate that this algorithm provides superior alignment performance than manual stitching and can be used to automatically align large imaging mass spectrometry datasets comprising many individual mosaic tiles. (J Am Soc Mass Spectrom 2008, 19, 823-832) © 2008 American Society for Mass Spectrometry I maging mass spectrometry is a rapidly developing analytical tool because it provides the ability to map the profiles of specific biomolecules, in which the intrinsic mass of the molecule differentiates between any modified forms; to record the distributions of multiple analytes in parallel; and to perform these analyses without a label and with clinical samples [1]. This combination of specificity, parallel detection, and non-targeted analysis has led to great excitement for its potential as a discovery tool.…”

“…Recent advances in both ionization efficiency (polyatomic primary ions) and sample preparation have significantly improved the sensitivity for detecting intact, medium-sized molecular ions (Ïœ1000 Da) from tissues and cells [1][2][3][4][5][6]. High-resolution images of small peptides, lipids, cholesterol, vitamins, and pharmaceuticals have all been reported, and through the use of large polyatomic primary ions three-dimensional (3D) molecular imaging results are beginning to appear [7][8][9].…”
