Book Synopsis Capillary Electrophoresis of Nucleic Acids by : Keith R. Mitchelson
Download or read book Capillary Electrophoresis of Nucleic Acids written by Keith R. Mitchelson and published by Springer Science & Business Media. 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.

Book Synopsis Capillary Electrophoresis of Proteins and Peptides by : Mark A. Strege

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.

Book Synopsis The Analysis of Biological Samples Using Capillary Electrophoresis and HPLC Technologies by :
Download or read book The Analysis of Biological Samples Using Capillary Electrophoresis and HPLC Technologies written by and published by . This book was released on 2007 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis (CE) and high performance liquid chromatography (HPLC) are two very important separation techniques. CE is a microseparation technique in which an electric field is applied to perform the separation. In CE, charged species are separated based on their charge/mass ratio, making this technique useful for separating a wide variety of components, including those found in biological samples. HPLC is the most widely used separation technique due to the ease of use and wide variety of components that can be separated. HPLC employs the use of pressure to push mobile phase through an analytical column containing a stationary phase that interacts with the solutes to effect the separation. Both CE and HPLC can use a number of different detection schemes to monitor the separated species, including ultra-violet (UV), laser-induced fluorescence (LIF), and mass spectrometry (MS). Affinity capillary electrophoresis (ACE) combines the separation power of CE with the selectivity of immunoassays. A fluorescein labeled estradiol derivative was evaluated for potential use as a competitive inhibitor in ACE. The labeling procedure rendered multiple components with the fluorescein label. Two of the components were identified as active estradiol species against the anti-estradiol antibody, examined by CE-LIF. Since only one active species had been predicted, both species were characterized using CE-MS and MS/MS, in addition to testing them in the ACE format. Nucleoside reverse transcriptase inhibitors (NRTIs) are one class of anti-HIV (human immunodeficiency virus) drugs. Because HIV is considered a pandemic, the analysis of NRTIs in human samples is very important; people all over the world are using these drugs. Currently, multiple NRTIs are given for treatment; however, there are few methods to date that separate and detect multiple NRTIs in a single run. NRTIs are metabolized in the body into their active triphosphate form. Two approaches can be followed for their separation and detection. The first approach was an indirect method, in which the active triphosphate form was dephosphorylated into the parent form of the NRTIs. HPLC with UV detection was utilized to establish an optimized separation method prior to using LC-MS/MS for the analysis of the following NRTIs in human peripheral blood monunclear cells (PBMCs): stavudine (D4T), lamivudine (3TC), the metabolized form of didanosine (ddA), zidovudine (ZDV), and the internal standard. The second approach was a direct method, in which analysis of the triphosphate form of the NRTIs was performed without dephosphorylation of the drugs. A capillary eletrophoretic method was developed that allows separation of the triphosphate NRTIs of interest: zidovudine triphosphate (ZDV-TP), stavudine triphosphate (D4T-TP), lamivudine triphosphate (3TC-TP), 2',3'-dideoxyadenoine triphosphate (ddA-TP), tenofivir diphosphate (TFV-DP), and emtricitabine triphosphate (FTC-TP). The separation was optimized using UV detection. Since UV detection does not offer appropriate detection limits, we studied the native fluorescence spectroscopic characteristics of the triphosphate NRTIs. We constructed an in-house CE-LIF system to explore LIF detection of the phosphorylated NRTIs. The system employed the use of a deep-UV laser with excitation at 224 nm. A sheath-flow cuvette was integrated into the design to improve detectability. The CE-LIF system was aligned and tested using the native fluorescence of tryptophan. The CE-LIF system was then used for the analysis of the active metabolized forms of NRTIs. With this system, we were able to separate and detect ZDV-TP, D4T-TP, 3TC-TP, ddA-TP, and the internal standard using a modification of the separation conditions previously optimized with UV detection. The detection limits obtained are not sufficiently low for the analysis of human PBMCs.

Download or read book Capillary Electrophoresis in the Early Twenty-first Century written by Dr. Oscar Núñez and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis (CE) comprises a family of related separation techniques in which an electric field is used to achieve the separation of components in a mixture. One of the key features of CE is the simplicity of the instrumentation required, and today, these techniques have become powerful analytical tools for high efficiency separation, and the identification of a variety of ionic and neutral compounds. Moreover, the versatility of CE operational modes (capillary zone electrophoresis, micellar electrokinetic capillary chromatography, capillary electrochromatography, capillary isoelectric focusing, isotachophoresis, non-aqueous capillary electrophoresis, etc.) and detection systems (ultraviolet, fluorescence, amperometric, mass spectrometry...) make CE useful for applications in many fields such as environmental, food, pharmaceutical, and forensic analysis. The typcial drawback of CE techniques, based on their low sensitivity when dealing with conventional UV-detection, due to their short detection pathways and the short sample volume introduced into the capillary, has been largely resolved not only by using more sensitive detectors like fluorescence, amperometric, or mass spectrometry, but by the employment of both off-line and on-line enrichment procedures. The aim of this present book is to address the state-of-the art of capillary electrophoresis techniques within this early twenty-first century, by reviewing new trends and the most relevant applications described in the literature. Uses in fields such as food, environmental, forensic and biological analysis are addressed by means of relevant application. The scope of this book is intentionally broad and is aimed at worldwide analytical laboratories, both public and private, at acadamic institutions, as well as researchers.

Book Synopsis Development of Analytical Protocols for Rapid Analysis of Biological Samples with Flow-gated Capillary Electrophoresis by : Ning Zhang
Download or read book Development of Analytical Protocols for Rapid Analysis of Biological Samples with Flow-gated Capillary Electrophoresis written by Ning Zhang and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development and improvement of the whole society, people are paying more attention to their health and the protection of the environment, which requires researchers to consider better identification and detection methods for various molecular species. Capillary electrophoresis (CE) and related technologies have been used in the separation, detection, and identification of many organic and inorganic compounds for the past dozens of years because of the advantages of CE, like short analysis time and high separation efficiency. Also, numerous detectors and interfaces can be combined with CE due to the excellent adaptability in order to enhance the performance of detection sensitivity, e.g., laser-induced fluorescence (LIF), mass spectrometry (MS), and electrochemical detection. This thesis is to discuss the determination of essential biomarkers in biological samples on the flow-gated CE-LIF system. It first reports a rapid and sensitive method with the flow-gated CE-LIF system to determine collagen degradation products, including proline, hydroxyproline, and other prolyl dipeptides in human urine samples, which is suited for the early diagnosis of collagen-related diseases. Experimental results prove that this method was capable of the separation and determination of prolyl compounds with good reproducibility, accuracy, sensitivity, and robustness. Second, the utilization of solid-phase extraction (SPE) in the purification and concentration of catecholamines (CAs) highlights the effectiveness of this method as a sample pre-treatment technique for catecholamines in real samples. By effectively removing interfering compounds and enhancing the concentration of the target analytes, SPE contributes to the overall reliability and accuracy of CA analysis.
