Book Synopsis Towards Proteome-on-a-chip by : Rafał Marszałek
Download or read book Towards Proteome-on-a-chip written by Rafał Marszałek and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Column-based separation techniques, such as liquid chromatography and capillary electrophoresis (CE), are often used to facilitate the hyphenation and sample transfer to a spectroscopic analysis stage due to their ability to be operated in a highly automatic and high-throughput style. Although there is some evidence in the literature for the use of capillary electrophoresis to deposit samples on a solid substrate for further analysis with mass spectrometry (MS) or other techniques, only a few examples of continuous deposition have so far been demonstrated. All of these, moreover, deposit sample at high substrate velocities, leading to the analyte zones spread over large distances and to decreased signal density in the subsequent analysis. Additionally, it is mainly MS that is used for sample analysis (with only one example of protein immunoblotting detection demonstrated). Recent developments in the field of infrared spectroscopy have, however, led to the invention of novel techniques, e.g. electron-vibration-vibration two-dimensional infrared spectroscopy (EVV 2DIR), which can be used for protein identification, quantification and other analysis. In this thesis a new workflow for top-down proteomic analysis (i.e. analysis of intact proteins) is proposed. In this strategy a number of mild separation steps - either fractionating the sample with size exclusion chromatography, sucrose gradients etc. or purification with affinity chromatography - are followed by capillary zone electrophoresis. CE is also used as an interface: the sample is slowly electrodeposited on the solid substrate. The speed of deposition ensures the high degree of analyte zone concentration on the substrate - leading to higher signal density and thus improving the sensitivity of any subsequent analysis. Finally, different optical read-out methods are employed for protein identification and quantitation, namely EVV 2DIR, modified Western blotting and imaging of the protein intrinsic (tryptophan) fluorescence. As the first step to establishing the workflow, an automated capillary electrophoresis instrument with a deposition interface was built and characterised in terms of its reproducibility. It was shown that an excellent migration time reproducibility of less than 0.5% can be achieved. Some inherent limitations of the interface are discussed in the thesis and the importance of the buffer system choice is emphasised. Additionally, a number of buffer systems were characterised in terms of their spectral and other properties to facilitate that choice. The interface platform was then applied to demonstrate feasibility of hyphenation between capillary electrophoresis and EVV 2DIR spectroscopy. In the proof-of-principle experiment five peptides were separated with CE, deposited on the solid substrate and subsequently imaged with intrinsic fluorescence read-out and EVV 2DIR. It was demonstrated that the peptide separations with the number of theoretical plates reaching 105 are attainable and the sample can be successfully deposited without loss of resolution. Due to the yet limited sensitivity of 2DIR read-out the final spectra of the deposited peptides were not obtained. As an alternative approach, coupling with the Western blotting read-out was suggested. Here, the chaperonin containing TCP-I was affinity purified, its subunits fractionated with CE and deposited on the nitrocellulose coated slides. The procedure was completed with the immunoblotting analysis. A proof-of-principle experiment was completed and the possible further improvements to the setup are discussed at length. 4.
Book Synopsis 2-D Proteome Analysis Protocols by : Andrew J. Link
Download or read book 2-D Proteome Analysis Protocols written by Andrew J. Link and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the completion of sequencing projects and the advancement of a- lytical tools for protein identification, proteomics—the study of the expressed part of the genome—has become a major region of the burgeoning field of functional genomics. High-resolution 2-D gels can reveal virtually all p- teins present in a cell or tissue at any given time, including posttranslationally modified proteins. Changes in the expression and structure of most cellular proteins caused by differentiation or external stimuli can be displayed and eventually identified using 2-D protein gels. 2-D Proteome Analysis Protocols covers all aspects of the use of 2-D protein electrophoresis for the analysis of biological problems. The contri- tors include many of the leaders in the fields of biochemistry and analytical chemistry who were instrumental in the development of high-resolution 2-D gels, immobilized pH gradients, computer analysis, and mass spectromet- based protein identification methodologies. This book is intended as a benchtop manual and guide both for novices to 2-D gels and for those aficionados who wish to try the newer techniques. Any group using protein biochemistry—especially in the fields of molecular biology, biochemistry, microbiology, and cell biology—should find this book eminently useful. 2-D Proteome Analysis Protocols takes the researcher through the c- plete process of working with 2-D protein gels from making the protein - tract to finally identifying the proteins of interest. It includes protocols for generating 2-D protein extracts from most of the standard model organisms, including bacteria, yeast, nematode, Drosophila, plants, mouse, and human.
Book Synopsis Two-Dimensional Electrophoresis Protocols by : David Sheehan
Download or read book Two-Dimensional Electrophoresis Protocols written by David Sheehan and published by Humana Press. This book was released on 2009-07-24 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human genome and other large-scale genome sequencing projects have inevitably led to a focus on the proteins encoded by genes. The field of proteomics has grown enormously as a result and a number of high-throughput technologies have now been developed allowing discovery-led investigations of protein populations rather than more traditional hypothesis-led studies on single proteins. These high-throughput techno- gies include gene and protein microarrays, the yeast two-hybrid system, and various mass spectrometry methodologies. However, despite developments and improvements in these technologies, two-dimensional electrophoresis (2DE) remains one of the most widely used approaches. This technique was revolutionised by the development of immobilised pH gradient strips which are now commercially available. This has made possible highly reproducible separations of matched samples. Developments in staining, mass spectr- etry, and bioinformatics supported these developments and have led to a measure of standardisation in design, execution, and analysis of proteomics experiments. This book began life as a proposed update of the excellent volume 2DE Protocols edited by Andrew Link of the University of Washington at Seattle. However, we re- ised that 2DE has undergone major development in aspects of its technology in recent years and we were anxious to reflect these in the present volume. We are also conscious that many researchers have now begun to apply proteomics methodologies to a growing range of biological material and we were anxious to include contributions to reflect the challenges posed in sample preparation in less widely used organisms.

Available in PDF, EPUB and Kindle. Book excerpt: Throughout the more than 20 years that have followed the beginnings of capillary electrophoresis (CE), its application to the analysis of proteins and peptides has continued to be reliable, versatile, and productive. Over time, CE has matured to become a superb complement to HLPC, and in many cases has also evolved as an automated and quantitative replacement for conventional slab gel electrophoresis methods such as SDS-PAGE and isoelectric focusing. Within Capillary Electrophoresis of Proteins and Peptides, we have assembled contributions from researchers who are applying state-of-the-art CE for protein and peptide analysis, including topics that we believe are of great potential both in the present and for the future. In comparison to traditional separation methods, CE represents a miniaturized analysis technique (especially in its microchip-based format) that is highly dependent upon the basic fundamentals of effective sample recovery and high sensitivity detection. With these issues in mind, Chapters 1–4 describe recently developed approaches for both capillary coatings and analyte detection via laser-induced fluorescence. Since the discipline of biotechnology has established itself as a primary platform for the application of CE to the analysis of proteins and peptides, Chapters 5–7 demonstrate a variety of examples of the specific techniques that have been applied for the development of biopharmaceuticals and their commercialization. The methods covered here include also the analysis of oligosaccharides from glycoproteins.

Available in PDF, EPUB and Kindle. Book excerpt: Top-down proteomics (TDP) enables the proteome profiling of biological subjects at the proteoform level and understanding of differential functions associated with proteoform heterogeneity, such as sequence variation, post-translational modifications (PTMs), etc. Drastic advances on TDP technologies (e.g. sample preparation, separation/fractionation, fragmentation, bioinformatics, etc.) have been achieved in the past decades. Further improvements in separation remain desired for better analysis throughput and deeper proteome coverage. Capillary electrophoresis (CE), including capillary zone electrophoresis (CZE) and capillary isoelectric focusing (cIEF), provide superior separation performance for proteoforms. This dissertation focuses on the advancement of CE-MS-based tools on throughput, separation resolution, and capacity for TDP and utility of these tools for biological applications.In Chapter 2, we developed high-throughput and high-capacity cIEF-MS/MS platforms. The high-throughput platform enables efficient identification and quantification of proteoforms (less than one hour per run), whereas the high-capacity cIEF-MS/MS provides large number of proteoform identifications (IDs, more than 700 proteoforms in a single shot analysis) which is valuable for deep TDP. In Chapter 3, we further improved the stability and robustness of cIEF-MS platform using optimized linear polyacrylamide (LPA) capillary coating and catholyte with lower pH (pH~10). The work achieved high-resolution characterization and accurate isoelectric point (pI) determination of charge variants (~0.1 pI difference) of monoclonal antibodies (mAbs). In Chapter 4, we developed a nondenaturing cIEF-MS platform for ultrahigh resolution characterization of microheterogeneity of a variety of protein complexes. Typically, pI determinations of variants in protein complexes allow us to decipher how sequence or PTM variations modulate the pIs of the protein complexes. In Chapter 5, while CZE-MS/MS is a well-developed approach, for the first time, we coupled FAIMS to CZE-MS/MS to facilitate online gas-phase fractionation of proteoforms. The FAIMS greatly enhanced the sensitivity of the system and expanded the number of proteoform IDs, especially large proteoform IDs. The work renders CZE-FAIMS-MS/MS as a new powerful multidimensional platform for deep TDP.In Chapters 6 and 7, we applied cIEF-MS/MS and CZE-MS/MS for studying the sexual dimorphism of zebrafish brains and proteoform-level differences between metastatic and nonmetastatic colorectal cancer (CRC) cells, respectively. In Chapter 6, quantitative TDP of thousands of proteoforms from male and female zebrafish brains by cIEF-MS/MS based approach discovered various overexpressed proteoforms in male or female brains that are closely associated with hormone activity. In Chapter 7, We performed deep TDP study of non-metastatic and metastatic CRC cells (SW480 and SW620) using CZE-MS/MS based multidimensional platform and identified more than 20,000 proteoforms of over 2,000 proteins from the two cell lines, which presents around 5-folds higher number of proteoform IDs in comparison with previous TDP studies of human cancer cells. The work revealed significant discrepancies between the two isogenic cell lines regarding proteoform and single amino acid variant (SAAV) profiles. Quantitative data disclosed differentially expressed proteoforms between the two cell lines and their corresponding genes were connected to cancer pathways and networks.
