Filling the gap created over the past five years, during which many new techniques have entered the market, this book is directed at both the new and the experienced ion channel researcher wishing to learn more about the considerations and methods for studying recombinant ion channels.
These latest developments are covered here for the first time, contributed by editors and authors working for major pharmaceutical companies and who routinely apply these techniques in their daily work. The first three chapters cover the use of the Xenopus oocyte expression system for structure-function studies, from basic approaches for manipulating ion channel cDNAs to more specialized but powerful techniques. This is followed by reviews of strategies and methodologies available for expressing channels in mammalian cells and for their analysis by patch-clamp electrophysiology. Chapters 6 to 8 review the latest methodologies for ion channel drug discovery, including high throughput screening using fluorescence and luminescence, as well as automated planar array electrophysiology. The remaining two chapters focus on approaches for determining ion channel crystal structures and on computational approaches to understanding channel mechanisms at atomic resolution.
Rather than provide detailed protocols, indicated by references in each chapter, the authors provide a comprehensive and easily accessible overview of the techniques involved, reviewing underlying principles and providing working guidelines as well as an understanding of the key theoretical and practical considerations associated with each topic. In each case, this practical advice is illustrated by real life examples, taken either from the author's own experience or from key examples in the literature, providing valuable practical hints not found elsewhere.
The result is a compendium of practical ion channel information that will prove a valuable resource to academic and industrial workers alike.
About the Author: Jeff Clare has worked in ion channel drug discovery for the last 13 years and is currently Head of Gene Expression for ion channels at GlaxoSmithKline. Having obtained his PhD from Kent University, he spent 5 years studying retrotransposable elements at UMIST and University of Connecticut. He then entered the pharmaceutical industry first joining Wellcome BioTech, to develop expression systems for vaccine antigen production, before transferring to Wellcome Research to initiate efforts in ion channel molecular cloning and expression. Subsequently, at GlaxoWellcome and then GlaxoSmithKline, he has been engaged in drug discovery and research projects for a range of ion channels, particularly voltage-gated sodium channels.

Derek Trezise has over fifteen years experience in the functional analysis of ion channels, in both academic and industrial environments. After completing his PhD on smooth muscle K+ channels at the Victoria University of Manchester, UK he spent 5 years as a postdoctoral researcher at the Glaxo Institute of Applied Pharmacology at Cambridge, studying P2X channels. He then moved to GlaxoSmithKline R&D, Stevenage where he has held positions of increasing responsibility in Neuroscience, Molecular Pharmacology and Assay Development and Compound Profiling departments. His current role is Head of Assay Development for ion channels and G-protein coupled receptors.
