This book was released on 2010 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis with laser-induced fluorescence detection (CE-LIF) is a versatile and sensitive analytical tool with many potential applications. Its advantages over other chromatographic methods include minimal solvent and sample requirements, low waste volumes, simple instrumentation, and diversity of analytes studied. CE is one of the most efficient separation techniques available for the analysis of both large and small molecules, but because few analytes are natively fluorescent, it is necessary to bind them with fluorescent tags if LIF detection is to be employed. These tags increase sensitivity and provide additional separation from components of the sample that do not bind the tags. In this dissertation, four applications of CE-LIF for the determination of tagged analytes are documented. First, a rapid CE-LIF method was developed for the determination of gamma-aminobutyric acid (GABA) and other important brain biogenic amines and amino acids present in biological samples at low levels. The high efficiency and sensitivity necessary to identify toxicologically relevant changes in neurotransmitter levels in brain tissue and microdialysates following Mn exposure was achieved, and the method required minimum sample work-up and quantities of sample for analysis. A linear relationship between the concentration of GABA and the CE-LIF peak height was established, with correlation coefficients of 0.989 or better for four neurotransmitters. Second, the use of two squarylium-based fluorescent dyes (bis-SQHN-4d and SQHN-3c) as noncovalent protein labels was investigated. The fluorescence emissions of both dyes were enhanced upon complexation with model proteins, demonstrating promise as noncovalent fluorescent protein labels. Third, the nature of interactions between two boronic acid-based probes (SQTM-BA1 and ANQW-BA1) and two model proteins (bovine serum albumin (BSA) and hemagglutinin (HA)) have been explored. The complex between SQTM-BA1 and BSA was the only complex to show increased fluorescence emission, and the role of electrostatic interactions between SQTM-BA1 and BSA in complex formation was explored. Lastly, CE-LIF methods were developed to label and quantify turnip yellow mosaic virus (TYMV). Noncovalent labels Red-1c and NN127 effectively labeled the surface proteins of the virus, and the labeled viruses were then analyzed by CE-LIF. The CE-LIF methods developed herein for the analysis of neurotransmitters, free solution proteins, and viruses demonstrate the versatility of the technique, especially when coupled with fluorescent labeling.
Book Synopsis Enhancing Detection Sensitivity for Measuring Amino Neurotransmitters with Flow-gated Capillary Electrophoresis by : Naveen Maddukuri
Download or read book Enhancing Detection Sensitivity for Measuring Amino Neurotransmitters with Flow-gated Capillary Electrophoresis written by Naveen Maddukuri and published by . This book was released on 2020 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis (CE) commences as a promising technique for analyzing a variety of biological substances and has been used in bioanalytical and biopharmaceutical applications. Flow-gated CE has numerous advantages over conventional and microchip CE. It has the advantage of fresh background electrolyte, improved separation efficiency, and PDMS flow-gate is easy for visual troubleshooting. However, it fails to have enough sensitivity in numerous valuable applications. The goal of the present research is to enhance the detection sensitivity in flow-gated CE for the measurement of amino neurotransmitters by using an integrated microfluidic system to perform in vitro and in vivo analysis of biological samples. This dissertation focuses on the development of novel methods to enhance the signal sensitivity for the detection of important molecular components in biological samples using laser-induced fluorescence detection. First, an efficient tagging strategy was developed to tag amino acids by taking advantage of the fast kinetics of the derivatization of primary amines with ophthalaldehyde (OPA) in the presence of a highly fluorescent thiol. Experimental results show that this strategy was capable of performing rapid fluorescent derivatization, thus providing detection sensitivity, reproducibility, accuracy, and robustness. Second, an on-line sample preconcentration technique based on vacuum-assisted electrokinetic supercharging (EKS) was developed for flow-gated CE to enhance the signal sensitivity of low abundant amino neurotransmitters, such as gamma-aminobutyric acid (GABA), glutamate and aspartate. The developed vacuum-assisted EKS technique was used to determine the GABA concentration in cerebrospinal fluid (CSF) samples by using the one-point standard addition method. Both techniques are anticipated to be valuable for in vivo measurements of neurotransmitters in neuroscience research and drug development.
Book Synopsis Clinical and Forensic Applications of Capillary Electrophoresis by : John R. Petersen
Download or read book Clinical and Forensic Applications of Capillary Electrophoresis written by John R. Petersen and published by Springer Science & Business Media. This book was released on 2001-04-20 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because capillary electrophoresis (CE) is driving the automation of manual and semi-manual techniques, conserves precious samples, and minimizes the use of hazardous organic chemicals, it constitutes a powerful new methodology for the clinical laboratory. In Clinical and Forensic Applications of Capillary Electrophoresis, John R. Petersen and Amin A. Mohammad, along with a panel of leading basic and clinical investigators, review those CE methods that are now replacing many routine serum and blood tests in clinical and forensic laboratories. Major areas reviewed include the coating of columns; the analysis of serum, urine, and CSF proteins and paraproteins; abnormal hemoglobins and hemoglobin Alc; peptides, amino and organic acids; therapeutic drugs; drugs of abuse; viral load; and short tandem repeats (STR). The methods discussed include capillary zone, micellar, electrokinetic, capillary gel, and nonaqueous electrophoresis. The authors show how a variety of detection methods (UV-visible, fluorescence, and MS) can be used in conjunction with CE to detect a broad array of analytes, ranging from serum proteins to PCR products to drugs of forensic importance. Innovative and highly practical, Clinical and Forensic Applications of Capillary Electrophoresis demonstrates the power and versatility of CE-not only to develop new assays, but also to markedly simplify today's clinical and forensic laboratory methodology.

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.

Download or read book Subattomole Amino Acid Analysis by Laser-Induced Fluorescence written by YF. Cheng and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subattomole analysis of fluorescein isothiocyanate (FITC) derivatives of amino acids is produced by combining capillary zone electrophoresis for high-efficiency separation with laser-induced fluorescence for high sensitivity detection. To optimize the separation process, several buffer systems were investigated. A pH 10 carbonate buffer provided good separation of 14 FITC amino acids. Concentration detection limits range from 5 x 10-12M for alanine to 9 x 10-11M for lysine, injected onto the column; ~9 x 10-21 mol of alanine is contained within the ~1-nL injection volume at the detection limit. The alanine detection limit corresponds to less than 6000 molecules injected onto the column and represents a four order of magnitude improvement in the state of the art for fluorescent detection of amino acids and a six order of magnitude improvement in the state of the art for the detection limit for isothiocyanate derivatives of amino acids.

This book was released on 2012-12-06 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, high performance Capillary electrophoresis (HPCE) has emerged as a powerful and versatile separation technique that promises to rival high performance liquid chromatography when applied to the separation of both charged and neutral species. The high speed and high separation efficiency which can be attained using any of the various modes of HPCE has resulted in the increased use of the technique in a range of analytical environments. The procedures are, however, still in the early stages of development and several barriers remain to their adoption as the technique of choice for a range of analytical problems. One such barrier is the selection and optimization of the conditions required to achieve reproducible separations of analytes and it is in this area that this new book seeks to give assistance. The book is written by an international team of authors, drawn from both academic and industrial users, and the manufacturers of instruments. At its heart are a number of tables, divided into specific application areas. These give details of published separations of a wide range of archetypal analytes, the successful separation conditions and the matrix in which they were presented. These tables are based on separations reported since 1992 and are fully referenced to the original literature. The tables are supported by discussions of the problems that a particular area presents and the strategies and solutions adopted to overcome them. The general areas covered are biochemistry, pharmaceutical science, bioscience, ion analysis, food analysis and environmental science.
Book Synopsis Practical Capillary Electrophoresis by : Robert Weinberger
Download or read book Practical Capillary Electrophoresis written by Robert Weinberger and published by Elsevier. This book was released on 2000-04-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1980s, capillary electrophoresis (CE) joined high-performance liquid chromatography (HPLC) as the most powerful separation technique available to analytical chemists and biochemists. Published research using CE grew from 48 papers in the year of commercial introduction (1988) to 1200 in 1997. While only a dozen major pharmaceutical and biotech companies have reduced CE to routine practice, the applications market is showing real or potential growth in key areas, particularly in the DNA marketplace for genomic mapping and forensic identification. For drug development involving small molecules (including chiral separations), one CE instrument can replace 10 liquid chromatographs in terms of speed of analysis. CE also uses aqueous rather than organic solvents and is thus environmentally friendlier than HPLC. The second edition of Practical Capillary Electrophoresis has been extensively reorganized and rewritten to reflect modern usage in the field, with an emphasis on commercially available apparatus and reagents. This authoritative and very comprehensible treatment builds on the author's extensive experience as an instructor of short courses for the American Chemical Society and for industry. Illustrated with detailed diagrams of electrophoretic phenomena Offers step-by-step methods development schemes Presents techniques for developing quantitative, robust, and precise methods Includes an extensive troubleshooting guide Updates and greatly expands on the first edition-more than 50% of the text is new Written by an internationally recognized scientist who is an instructor for American Chemical Society short courses on HPCE

This book was released on 2008-02-05 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of PCR, which enables extremely small amounts of DNA to be amplified, led to the rapid development of a multiplicity of a- lytical procedures that permit use of this new resource for the analysis of genetic variation and for the detection of disease-causing mutations. The advent of capillary electrophoresis (CE), with its power to separate and a- lyze very small amounts of DNA, has also stimulated researchers to develop analytical procedures for the CE format. The advantages of CE in terms of speed and reproducibility of analyses are manifold. Furthermore, the high s- sitivity of detection, and the ability to increase sample throughput with par- lel analysis, has led to the creation of a full range of analysis of DNA molecules, from modified DNA adducts and single-strand oligonucleotides through PCR-amplified DNA fragments and whole chromosomes. Capillary Elect- phoresis of Nucleic Acids focuses on analytical protocols that can be used for detection and analysis of mutations and modification, from precise DNA loci through entire genomes of organisms. Important practical considerations for CE, such as the choice of separation media, electrophoresis conditions, and the influence of buffer additives and dyes on DNA mobility, are discussed in several key chapters and within particular applications.
