Capillary Electrophoresis Of Biomolecules

This book details key techniques used to investigate Capillary electrophoresis (CE). It focuses on simple and complex carbohydrates (polysaccharides), aminoacids, peptides and proteins, enzymes, and nucleic acids.

This new book on capillary electrophoresis (CE) is unique in its focus on biotechnology. It is devoted to proteins, peptides, and techniques especially useful in the area of recombinant DNA products. Emphasis is also placed on glycoproteins. Because of the growing role of the glycosylation process in CE, a comprehensive chapter on the subject acts as a book within a book. Although this well-known researcher in biotechnology presents a number of chapters extensively discussing theories, important practical aspects in the routine use of capillary electrophoresis are also covered.

The book describes the theory and applications of Capillary Electrophoresis (CE) in the field of pharmaceutical and biomedical analysis. It is targeted towards users who are intimately involved in analytical problems, especially those which involve small samples. This book presents the technique of capillary electrophoresis from the point of view of the serious hands-on use in the field of pharmaceutical and biomedical analysis. An overview of general theory is presented to acquaint the novice with the fundamental principles. A more theoretical approach is taken in the presentation of electrokinetic chromatography. The next chapter discusses advances in column technologies, the preceding chapters having provided a foundation as to how separations occur. In the next three chapters, recognized experts in their fields present fundamentals and state-of-the-art techniques in the areas of optical, electrochemical and mass spectrometric detection. The major focus of the remaining chapters is on applications. This includes the analysis of pharmaceuticals, amino acids and peptides, macromolecules, nucleosides, nucleotides and oligonucleotides. The use of CE for analysis of small ions and separation of biological particles is also discussed. The issue of sample preparation for analysis by CE is addressed, especially as it relates to clinical analysis.

Explores the benefits and limitations of the latest capillary electrophoresis techniques Capillary electrophoresis and microchip capillary electrophoresis are powerful analytical tools that are particularly suited for separating and analyzing biomolecules. In comparison with traditional analytical techniques, capillary electrophoresis and microchip capillary electrophoresis offer the benefits of speed, small sample and solvent consumption, low cost, and the possibility of miniaturization. With contributions from a team of leading analytical scientists, Capillary Electrophoresis and Microchip Capillary Electrophoresis explains how researchers can take full advantage of all the latest techniques, emphasizing applications in which capillary electrophoresis has proven superiority over other analytical approaches. The authors not only explore the benefits of each technique, but also the limitations, enabling readers to choose the most appropriate technique to analyze a particular sample. The book's twenty-one chapters explore fundamental aspects of electrophoretically driven separations, instrumentation, sampling techniques, separation modes, detection systems, optimization strategies for method development, and applications. Specific topics include: Critical evaluation of the use of surfactants in capillary electrophoresis Sampling and quantitative analysis in capillary electrophoresis Capillary electrophoresis with electrochemical detection Overcoming challenges in using microchip electrophoresis for extended monitoring applications Capillary electrophoresis of intact unfractionated heparin and related impurities Microchip capillary electrophoresis for in situ planetary exploration Each chapter begins with an introduction and ends with conclusions as well as references to the primary literature. Novices to the field will find this book an easy-to-follow introduction to core capillary electrophoresis techniques and methods. More experienced investigators can turn to the book for troubleshooting tips and expert advice to guide them through the most advanced applications.

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.

In the rapidly developing field of analysis it is important to be aware of the newest methods within available techniques. Chromatography and Capillary Electrophoresis in Food Analysis describes chromatographic and electrophoretic principles and procedures for analyses of various amphiphilic and hydrophilic biomolecules, particularly for food analysis. Providing basic information, including general sample preparation, the book then goes on to describe individual analytical methods and exemplify the strategy and methodologies employed for the analyses. The theory necessary to understand the methods and interpretation of results is also included, as are numerous detailed instructions on experiments. Tables, figures and references are included to give a complete picture. Chromatography and Capillary Electrophoresis in Food Analysis will be especially valuable for students and more experienced researchers interested in analysis of natural products, both inside and outside the field of food chemistry.

This book presents a selection of current capillary electrophoresis methods used to separate representative types of molecules and particles and in combination with different detection techniques. It includes practical details which are hard to find elsewhere. The volume is intended for beginners in the field and provides an overview of the technique and a starting point for the exploration of the defined literature on different application topics.
