With the latest advances in analytical technologies, most biological products can now be extensively characterized in terms of their identity, heterogeneity and impurity profile. The currently available analytical methods (both physicochemical and biological) can characterize the primary, secondary and to some extent, the higher order structure of proteins. The sensitivity and selectivity of these methods allow for the identification and characterization not only of the desired protein component, but also many product-related substances and impurities as well as process-related impurities present in the drug preparations. Using an appropriate selection of analytical tools, it may be possible to demonstrate physicochemical and functional comparability between protein products manufactured before and after a manufacturing change or during product development. However, the extent of demonstrable comparability depends on the tests used, on the nature of the product and on the basic understanding of structure-function relationships. Assessment of immunogenicity is also a critical component of product characterization and is highly dependent on the types of assays used.
The importance of capillary electrophoresis (CE) as an analytical tool has increased dramatically over the last ten years. It has changed from being an exploratory technique, mainly of academic interest, to one that is applied to solve "real" analytical problems. CE is easily adapted to its various modes of operation, often requiring little more than a change of the buffer solution, and is quickly becoming the preferred technique when analyzing minute amounts of available material. Featuring new chapters on CE analysis of inorganic ions and carbohydrates, the new edition of Capillary Electrophoresis not only presents this method as an academic tool, but also provides applications for solving "real-world" analytical problems. This updated Second Edition reflects the increasing use of CE over the last 10 years, how it is being applied, and the basic theoretical aspects of the separation and detection methodology of CE. Capillary Electrophoresis: Theory and Practice will appeal to students and professionals of analytical chemistry, physical chemistry, biochemistry, and biotechnology and includes suitable experiments designed to be attempted by university or college students, or anyone else wishing to familiarize themselves with CE.
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.
Because new information was discovered at an incredible rate since the publication of the successful first edition of this Handbook, this fully updated second edition covers all areas of interest in the field of capillary electrophoresis (CE). A relatively new technology, CE is a principle method for studying the physicochemical properties of proteins, peptides, and other macromolecules. Where applicable, the 30 chapters provide basic underlying theories as well as application-oriented aspects of each technique.Keep up with all the developments in this growing field with the Handbook of Capillary Electrophoresis, Second Edition - a complete guide to the fundamentals of CE and the latest research. The chapters are organized into five units: Modes: Presents a theoretical development of the basic principles governing separation with several modes, including CEC, and discusses their practical aspects. Analyte: Applies CE to the analysis of a specific class of analytes, including organic and inorganic ions, pharmaceuticals, glycoconjugates, peptides, proteins, and DNA fragments. Fundamental Aspects of CE: Technique-oriented information for the practitioner, including the importance of the sample matrix, on-line preconcentration of samples, modes of detection, and specific aspects of CE data analysis. Applications of CE: Includes single cell analysis, CE in DNA sequencing, CE as a clinical diagnostic tool, identifying and quantifying drugs, and for characterizing interacting species. Specialized Aspects of CE: Discusses interfacing CE with mass spectrometry, high-volume throughput continuous CE, microchip CE, control of EOF, and much more. The Handbook of Capillary Electrophoresis, Second Edition, pulls together diverse areas and applications of CE, resulting in an excellent tool for scientists involved in biotechnology and clinical chemistry, as well as the pharmaceutical, bioscience, chemical, and instrument-manufacturing industries. With an applications-oriented focus, the handbook is also a superb manual for workshops, seminars, and graduate courses in separation science.
This text aims to evaluate the actual impact of high-performance capillary electrophoresis on analytical biotechnology and environmental analysis. The first part of the book presents a survey of present innovations in instrument design and different methods of pre-concentration techniques in order to obtain increased separations at higher sensitivities. The second part contains articles on applications of HPCE to protein and peptide analysis. In the third part, applications of HPCE in the investigation of drug abuse and drug interactions are presented. The last two parts of the book deal with the use of HPCE at low-UV wavelengths and negative-UV absorption. The book should be of interest to those working in HPCE research and applications.
