Book Synopsis Advancing Capillary Electrophoresis-mass Spectrometry for Top-down Proteomics by : Tian Xu
Download or read book Advancing Capillary Electrophoresis-mass Spectrometry for Top-down Proteomics written by Tian Xu and published by . This book was released on 2023 with total page 0 pages. 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.

Book Synopsis Microfluidic Dynamic Isoelectric Focusing Coupled to Matrix Assisted Laser Desorption/ionization Mass Spectrometry by : Srikanth Akinapalli
Download or read book Microfluidic Dynamic Isoelectric Focusing Coupled to Matrix Assisted Laser Desorption/ionization Mass Spectrometry written by Srikanth Akinapalli and published by . This book was released on 2016 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteomics is an increasingly important area of biological research and has gathered much attention over recent years. Major challenges that make a proteomic analysis difficult are sample complexity, diversity and dynamic range. Progress in the area of proteomics relies heavily on new analytical tools for the sensitive, selective, and high-throughput studies of target analytes. It is estimated that there are several hundred thousand proteins in a human cell. In order to be able to analyze such a complex sample, an analytical method must be capable of separating and detecting many different sample peaks. The complexity of such samples indicates that a single separation method will not be able to provide the needed resolution. If two methods that are orthogonal are combined, then the peak capacity of the combined system is the product of the two individual peak capacities. Development of such systems would cater to the current demands of proteomics studies. Matrix assisted laser desorption/ionization (MALDI) mass spectrometry has evolved into a primary analytical tool for proteomics research. MALDI is fast and efficient and has a high tolerance to non-volatile buffers and impurities. The samples for MALDI are typically applied to solid supports after having been subjected to off-line liquid or gel separations. Several methods have been reported involving various chromatographic or electrophoretic separation methods. However, the current methods often require highly sophisticated sample handling systems, which are often expensive and in need of skilled human resources. The current demands of proteomic analyses require fast, efficient and inexpensive methods for separation to fully harness the capability of MALDI mass spectrometry. In this work a microfluidic device has been designed to perform dynamic isoelectric focusing (DIEF) based protein separation with digital sample deposition directly on a MALDI target for offline analysis. DIEF is related to capillary isoelectric focusing which and can facilitate the interface without the loss of the separation resolution. Compared to traditional capillary isoelectric focusing (cIEF) DIEF uses additional high-voltage power supplies to control the pH gradient by manipulating the electric field. The proteins can be focused at a desired sampling position according to their isoelectric point, to be collected for further analysis by MALDI mass spectrometry. DIEF has a peak capacity of over a thousand and offers an ease of interfacing to other techniques making it a preferred separation method for the interface with mass spectrometric techniques such as MALDI. The design of the microfluidic device is based on a digital droplet fractionation. Multiple fractions of the sample solution from DIEF are generated to retain the resolution and to act as an additional separation mode. The microfluidic device is controlled by actuating pneumatic valves built into the device. The DIEF operational parameters were optimized according to the surface functionality and the design of the microfluidic device. A suitable MALDI sample preparation method was found by studying different existing methods. The methods were studied using test proteins prepared in solutions having the additives used in the experiment. A simple mixture of three proteins was used to demonstrate the application of the developed method. The separation between the proteins insulin, hemoglobin and the myoglobin was demonstrated by varying the separation resolution in three experiments.
Book Synopsis Development of Isoelectric Focusing Techniques for Protein Analyses by : Yanwei Zhan
Download or read book Development of Isoelectric Focusing Techniques for Protein Analyses written by Yanwei Zhan and published by . This book was released on 2008 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Isoelectric focusing (IEF) is a powerful approach in separations of zwitterionic substances such as proteins, peptides and amino acids. It is important in proteomic research. Generally, in IEF, carrier ampholytes (CAs) are necessary to establish a stable pH gradient. However, CAs also bring attendant problems such as a decrease in detection sensitivity and suppression of ionization of analytes in mass spectrometry (MS) detection. It is desirable to build a pH gradient without using CAs. A simple slab based design was developed to establish a pH gradient using the electrolysis of water and the strength of free flow electrophoresis (FFE). The simple and robust CA free FFE-IEF design was applied in protein fractionation. In capillary format, capillary isoelectric focusing (CIEF), coupled to MS is a promising hyphenated technique for biomolecular analysis based on the combination of the high separation power of CE and the high specificity of MS. Coupling of the instruments is usually achieved with a coaxial sheath liquid interface, which decreases the detection sensitivity because of the dilution of sample by the sheath liquid. In this project, nano-electrospray, a sheathless interface, was used for coupling. Additionally, another major challenge is the presence of CAs which suppresses the ionization of analytes and contaminates the MS. In order to complete this project, a microcross union was chosen to couple CIEF with MS. A makeup solution was introduced to dilute the concentration of CAs after IEF to assist the ionization for MS detection. The makeup solution could replace the sheath liquid and could be maintained at a low flow rate so that nanoelectrospray could be performed. Monoliths can be described as integrated continuous porous separation media for micro scale separation columns. CAs were immobilized at different positions in the column according to their pIs, generating a monolithic immobilized pH gradient (M-IPG). In this project, carrier ampholytes was immobilized in poly (GMA-co-EDMA) based monolithic capillary and poly (GMA-co-acrylamide) based monolithic capillary to form a pH gradient. Two proteins were separated by IEF, which was implemented in poly (GMA-co-acrylamide) based monolithic capillary without CAs. The interface to MS was performed following the use of a microcross union as described previously. No typical noise of CAs was observed in the MS spectrum.

Download or read book Leveraging Capillary Zone Electrophoresis-mass Spectrometry for Multi-level Proteomics written by Xiaojing Shen and published by . This book was released on 2020 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometry (MS) coupled with online liquid-phase separation is the major tool for large-scale bottom-up proteomics (peptide-centric), top-down proteomics (proteoform-centric), and native proteomics (protein complex-centric). While liquid chromatography (LC)-MS is the dominant method for proteomics at different levels, capillary zone electrophoresis (CZE)-MS has emerged as a valuable and complementary technique, which provides high-capacity separation and highly sensitive detection of peptides, proteoforms and even protein complexes under native conditions. This work focuses on developing novel CZE-MS/MS methods for multi-level proteomics (bottom-up, top-down, and native).In Chapter 2, a high-throughput bottom-up proteomics workflow was developed by coupling immobilized trypsin-based speedy protein digestion with fast CZE-MS/MS. Immobilized trypsin produced almost the same digestion performance as free trypsin for complex proteomes with about 50-times higher speed (15 min vs. 12 h). Integration of immobilized trypsin (IM)-based rapid protein cleavage and fast CZE-MS/MS enables the identification of thousands of proteins from the mouse brain proteome in only 3 h, which is significantly faster than the typical LC-MS-based bottom-up proteomics workflow (3 h vs. >12 h). The high-throughput workflow was expected to be useful for bottom-up proteomics of human clinical samples (e.g., serum and urine).Chapter 3 presents the first example of CZE-MS/MS with activated ion-electron capture dissociation (AI-ECD) on a high-end quadrupole-time-of-flight (Q-TOF) mass spectrometer for top-down proteomics, enabling high-resolution separation, highly sensitive detection, and extensive gas-phase backbone cleavages of proteoforms. The CZE-AI-ECD method will be useful to the top-down proteomics community for the comprehensive characterization of proteoforms in complex proteomes. Chapter 4 and 5 focus on the development of novel CZE-MS methods for native proteomics, delineating proteins and protein complexes under native conditions. In Chapter 4, a native CZE-MS/MS platform with an Orbitrap mass spectrometer was established for native proteomics of a complex proteome (E. coli), leading to the identification of 23 protein complexes in discovery mode. The work represents the first example of native proteomics via coupling online liquid-phase separation to native MS and MS/MS. The characterization of large protein complexes (up to 200 kDa) was also achieved with a new CZE-MS system on a high-end Q-TOF mass spectrometer.In Chapter 5, a novel native capillary isoelectric focusing (cIEF)-assisted CZE-MS method is presented for the characterization of monoclonal antibodies (mAbs) with large sample loading capacity and high separation resolution. Using the method, the potential separations of different conformations of the SigmaMAb and the detection of its various glyco-proteoforms and homodimer were documented. The method separated the NISTmAb into three peaks with a microliter sample loading volume, corresponding to its different proteoforms. In addition, eight glyco-proteoforms of the NISTmAb and its homodimer were detected. The results demonstrate the potential of the native cIEF-assisted CZE-MS method for advancing the characterization of large proteins (i.e., mAbs) and protein complexes under native conditions.
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.

This book was released on 2008-02-04 with total page 340 pages. 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.
