The use of High Performance Liquid Chromatography (HPLC) techniques in the study of enzymatic reactions has grown significantly since the publication of the first edition of this highly successful book: the role of enzymes in biological research has expanded; the application of HPLC and enzymes has extended to more disciplines; advances in separation techniques and instrumentation have increased the capability of HPLC; and the discovery of new enzymes has spawned new methods of analysis.
High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition addresses these developments in its coverage of the refinements of HPLC methods and their use in a wide range of laboratory applications. It offers the same practical approach found in the first edition, incorporates a wealth of new information into existing chapters, and adds new chapters to deal with new applications, including capillary electrophoresis, forensic chemistry, microdialysis, and the polymerase chain reaction. Topics include:
* Application of HPLC to the assay of enzymatic activities
* Concepts and principles of HPLC, including the latest technological advances

"It is the ability of HPLC to accomplish separations completely and rapidly that led to its original application to problems in the life sciences, particularly those related to purification. An analysis of the literature revealed that this technique was used primarily for the purification of small molecules, macromolecules such as peptides and proteins, and more recently, antibodies. This application to purification has all but dominated the use of the method, and there has been a plethora of books, symposia, and conferences on the use of HPLC for these purposes. However, it was only a matter of time before others began to look beyond and to explore the possibilities that result from the capacity to make separations quickly and efficiently." --from the preface to the First Edition
Easy to read and full of practical advice and hundreds of diagrams and examples, High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition is an invaluable resource for students, researchers, and laboratory workers in analytical chemistry and biochemistry, molecular biology and cell biology, and for anyone interested in keeping up with this fast-growing field.
Gradient elution demystified
Of the various ways in which chromatography is applied today, few have been as misunderstood as the technique of gradient elution, which presents many challenges compared to isocratic separation. When properly explained, however, gradient elution can be less difficult to understand and much easier to use than often assumed.
Written by two well-known authorities in liquid chromatography, High-Performance Gradient Elution: The Practical Application of the Linear-Solvent-Strength Model takes the mystery out of the practice of gradient elution and helps remove barriers to the practical application of this important separation technique. The book presents a systematic approach to the current understanding of gradient elution, describing theory, methodology, and applications across many of the fields that use liquid chromatography as a primary analytical tool.
This up-to-date, practical, and comprehensive treatment of gradient elution:
* Provides specific, step-by-step recommendations for developing a gradient separation for any sample
* Describes the best approach for troubleshooting problems with gradient methods
* Guides the reader on the equipment used for gradient elution
* Lists which conditions should be varied first during method development, and explains how to interpret scouting gradients
* Explains how to avoid problems in transferring gradient methods
With a focus on the use of linear solvent strength (LSS) theory for predicting gradient LC behavior and separations by reversed-phase HPLC, High-Performance Gradient Elution gives every chromatographer access to this useful tool.

Oxidative Stress and Antioxidant Protocols (Methods in Molecular Biology)
onald Armstrong updates and expands his highly praised Free Radical and Antioxidant Protocols (Humana, 1998) with a collection of new and valuable methods for evaluating the pertubations in cell function resulting from increased oxidative stress. Presented in a user-friendly, step-by-step format, these readily reproducible techniques cover both free radical-derived and antioxidant biomarkers. The methodologies demonstrated include ELISA, HPLC, infrared spectroscopy, gas chromatography-mass spectroscopy, immunoblotting, electroelution fractionation, isoelectric focusing, voltametry, and electron paramagnetic resonance imaging. Special emphasis is given to the separation of complex mixtures of plant antioxidants, soft drug design to protect from toxic oxidative metabolites, in vitro oxidation conditions, and correcting for random measurement error to improve statistical interpretation. A soon-to-be-published companion volume, Oxidants and Antioxidants: Ultrastructural and Molecular Biology Protocols (0-89603-851-3), contains state-of-the-art molecular and ultrastructural methods that expand the total number of protocols to 109 assays.

Development and Validation of HPLC Methods For Analytical And Preparative Purposes
Liquid chromatography (LC) is a separation method of great importance to the chemical, pharmaceutical and biotechnological industry. The principle is that a sample of a solution of the substances is injected into a column of an porous material (stationary phase) and a liquid (mobile phase) is pumped through the column. The separation of substances is based on differences in rates of migration through the column arising from different partition of the substances between the stationary and the mobile phase. Depending on the partition behavior of the different types of substances, these will elute at different times from the column outlet.
