Book Synopsis Development of High-sensitivity Atmospheric Pressure (AP) Matrix-assisted Laser Desorption/ionization (MALDI) and Open Air Ionization Techniques for the Analysis of Biomolecules by Mass Spectrometry by : Arti T. Navare
Download or read book Development of High-sensitivity Atmospheric Pressure (AP) Matrix-assisted Laser Desorption/ionization (MALDI) and Open Air Ionization Techniques for the Analysis of Biomolecules by Mass Spectrometry written by Arti T. Navare and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Matrix-assisted laser desorption/ionization (MALDI) has been celebrated as a soft ionization method for analyzing very diverse biological species including large proteins, peptides, carbohydrates, lipids and metabolites. The fact that MALDI is tolerant to salts and buffers and that it mostly produces singly charged ions from intact biomolecules is considered highly advantageous over electrospray ionization (ESI). Almost two decades after the introduction of vacuum MALDI, the technique was successfully implemented under atmospheric pressure (AP) conditions by Laiko and co-workers. Some of the most salient advantages of AP-MALDI over vacuum MALDI are its ability to generate intact ions from labile species with minimal fragmentation due to collisional cooling under AP, the ability of performing MSn experiments, and its exchangeability with other ion sources. However, AP-MALDI suffers from limited sensitivity due to low ion transmission efficiency under AP conditions. Because sensitivity is a function of the sample pretreatment method of choice, both preconcentration and selective sample fractionation can be used during the initial stages of the analytical pipeline to improve detectability. To that end, the first part of the work presented in this thesis is aimed at investigating various approaches to improve the sensitivity of AP-MALDI for mass spectrometric analysis of biomolecules. Chapter 1 reviews the history of laser desorption ionization (LDI), presenting salient features of vacuum MALDI and AP-MALDI, and concludes with a brief overview of leading ambient ionization techniques, such as Direct Analysis in Real Time (DART) ionization. Chapter 2 presents an investigation of an on chip sample preconcentration approach coupled to AP-MALDI for high-sensitivity analysis of neuropeptides extracted from Aedes aegypti mosquito heads. The theme of exploring efficient and reproducible purification methods for complex biosamples is continued in Chapter 3, where an evaluation of new on-tip solid-phase extraction (SPE) micro columns with various functional groups is presented. A second approach for enhancing AP-MALDI sensitivity by constructing a new pneumatically-assisted (PA) AP-MALDI ion source is presented in Chapter 4, where various factors affecting the performance of this device are investigated. Chapter 5 describes work involving the evaluation of DART ionization as a high-throughput method for the detection and identification of small terpene molecules central to the Aedes aegypti mosquito lifecycle.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of mass spectrometry has grown tremendously over the past few decades due in large part to the continued application to new and interesting areas of exploration. The advent of soft ionization sources such as electrospray ionization and matrix-assisted laser desorption/ionization have dramatically increased the capabilities of mass spectrometry and increased the amount of information derived from biological samples. As a result, there has been tremendous growth in the development of new ionization source technology in recent years. One of the main driving forces behind the development of new ionization technology is for the reduction of sample preparation required prior to analysis, yielding high throughput sample analysis. Demonstrated herein is the development and characterization of an atmospheric pressure ionization source called matrix-assisted laser desorption electrospray ionization (MALDESI). MALDESI is a hybrid combination of MALDI and ESI which utilizes laser desorption with electrospray postionization for the generation of multiply-charged ions. Multiply-charged ions are of particular importance when using Fourier transform mass spectrometry, due to the increase in resolving power and mass accuracy with increasing charge on the molecule. Top-down characterization of intact polypeptides is demonstrated as well as high mass accuracy utilizing internal calibration. A newly designed highly robust and versatile atmospheric pressure ionization platform is developed and described in detail. Solid- and liquid state analysis of three out of the four classes of biological molecules is demonstrated utilizing the newly developed versatile ionization platform. MALDESI utilizing ultraviolet and infrared laser desorption is demonstrated at various wavelengths (UV, 337 nm and 349 nm and IR, 2.94 Ã'Âæm and 10.6 Ã'Âæm) with and without ESI postionization for the generation of multiply-charged ions. The characteristics of liquid-state samples are described as a mac.

Book Synopsis Studies of Atmospheric Pressure Visible-wavelength MALDI-MS by : Zhen Sun
Download or read book Studies of Atmospheric Pressure Visible-wavelength MALDI-MS written by Zhen Sun and published by . This book was released on 2012 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matrix-assisted laser desorption/ionization technique (MALDI) is well proven as a soft and efficient ionization technique used in mass spectrometry (MS) for the analysis of biomolecules (such as sugars, peptides, DNAs, and proteins), and large organic molecules (such as synthetic polymers). While the technique has been developed in 1980s, the improvements in MALDI-MS instrumentation and search for new matrices have continued. In the first project of this thesis, an atmospheric pressure (AP) visible-wavelength MALDI source was developed and coupled to a quadrupole time-of-flight (Q-TOF) mass spectrometer. This instrument employed a pulsed laser emitting light at a wavelength of 532 nm to desorb and ionize samples such as dyes, oligosaccharides, peptides, and synthetic polymers at atmospheric pressure. Ions formed were analyzed by the Q-TOF in both MS and tandem MS (MS/MS) modes. Several visible-wavelength absorbing dyes were successfully utilized and studied as matrices. Among these dyes, nuclear fast red (NFR), rhodamine B isothiocyanate (RITC), and 5(6)-carboxytetramethyl-rhodamine N-succinimidyl ester (TAMRA, SE) are reported as effective visible-wavelength MALDI-MS matrices for the first time. This project demonstrates applicability of visible-wavelength AP MALDI-MS and AP MALDI-MS/MS to the detection and structural analysis of dye molecules, biomolecules such as sugars and peptides, and synthetic polymers. In the second project, the model protein lysozyme was modified with fluorescein isothiocyanate (FITC). 64% of lysozyme was conjugated with FITC. Crystallization of pure lysozyme and FITC-conjugated lysozyme were performed after protein purification and pre-concentration. Pure lysozyme samples formed very good crystals, but there was no crystal observed for FITC-conjugated lysozyme. These two samples were then analyzed by different sample preparation methods using MALDI-MS. However, only lysozyme crystal with UV MALDI matrix spotted on top of it worked well. By performing a series of experiments, we confirmed that: it is crucial to have a matrix for the analysis of a single lysozyme crystal and the lysozyme crystal has different crystal structure than the matrix-analyte co-crystal. Secondly, it has not been possible to form crystal with 64% of lysozyme being conjugated with FITC dye. In summary, we developed an AP visible-wavelength MALDI-MS methodology, which enabled the analysis of biomolecules and synthetic polymers. Visible-wavelength AP MALDI-MS and MS/MS analyses of a variety of samples at atmospheric pressure were presented for the first time. Several visible-wavelength absorbing dyes were successfully utilized as matrices, and three dyes were reported as novel visible-wavelength MALDI matrices. Additional experiments were performed to covalently attach FITC to lysozyme and crystallize fluorochrome-conjugated protein. MALDI-MS was employed to study crystals of unlabeled lysozyme, while crystallization of FITC-conjugated lysozyme needs to be optimized further.
