E. Neher and B. Sakman were the first to monitor the opening and closing of single ion channels and membranes by conductance measurements. In 1976, they used firepolished micropipets with a tip diameter of 3-5 pm to record currents from a small patch of the membranbe of sk- etal muscles, thereby decreasing background membrane noise. In order to reduce the dominant source of background noise-the leakage shunt under the pipet rim between m- the muscle membrane had to be treated brane and gla- enzymatically. Despite these early limitations, a new te- nique was born -the patch-clamp technique. The final bre- through came in 1981 when the same authors, in collaboration with 0. P. Hamill, A. Marty, and F. J. Sigworth, developed the gigaohm seal. Not only did this improve the quality of recordings, it was now possible to gently pull the membrane patch with the attached pipet off the cell and study its trapped ion channels in isolation. Another offshoot of the gigaohm seal technique was the whole-cell patch-clamp technique, in which the patch is ruptured without breaking the seal. This technique is really a sophisticated voltage-clamp technique and also allows for the altering of cytoplasmic constituents if the experimenter so wishes. The first part of Patch-Clamp Applications and Protocols presents modern developments associated with the techn- ogy of patch-clamp electrodes, of cell-free ion channel reco- ing, and of the whole-cell patch-clamp technique.

Patch Clamp Methods and Protocols surveys the typical patch clamp applications and advises scientists on identifying problems and selecting the best technique in each instance. The experiments described require a basic level of electrophysiological training and aid the researcher in pursuing new areas of electrophysiology and using the patch clamp technique effectively. Patch Clamp Methods and Protocols is divided into three sections that cover the major areas of patch clamp application: Pharmacology, Physiology, and Biophysics. The first section provides examples and step by step instructions on how to use whole-cell and single-channel patch clamp methods for testing drugs in industrial settings. The second section provides a wide selection of patch clamp applications in physiological studies. The last part focuses on the biophysical applications of the patch clamp method using single channel recordings or statistical analysis of whole-cell currents in order to obtain parameters that describe ion channel properties or transmitter release. Individual techniques are explored within the area that they are applied most often. Researchers will find Patch Clamp Methods and Protocols to be an invaluable aid in the design and execution of a wide variety of patch clamp experiments, both on their own and in conjunction with other state-of-the-art methodologies.

This volume describes a range of standard and novel methodological approaches used to probe ion channel function across different modalities. Chapters guide readers through methods and protocols from an introduction to the decades old patch clamp method for the ion channel neophyte to more complex, recent protocol advances, such as optogenetics. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, application details for both the expert and non-expert reader, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Patch Clamp Electrophysiology: Methods and Protocols aims to be a reference guide for current and future ion channel physiologists.

Channels and transporters are multi-functional proteins that mediate substrate transport and signal transmission and simultaneously act as regulators for other proteins and biosensors for environmental materials. Patch clamping is an epoch-making technique that allows researchers to perform real-time measurements of electrogenic channel/transporter functions at the single/multiple molecular level. This book describes not only the conventional patch clamp techniques but also their newly developed variations or applications, such as perforated patch, slice patch, blind patch, in vivo patch, imaging patch, smart patch, and automated patch clamping. These patch clamp techniques are now essential and are extensively used across the life sciences and in related industries. With plain and practical descriptions of patch clamping and how to carry it out, especially for beginners, the book also shows how widely and exquisitely the patch clamp techniques can be applied by expert electrophysiologists. This work serves as a useful guide for young researchers and students in training and laboratory courses as well as for senior researchers who wish to extend their repertoire of techniques.

Patch-Clamp Analysis: Advanced Techniques describes in reproducible detail all applications that involve patch pipet. Beginning with updated basic patch-clamp techniques, the book presents the newest developments, ranging from fast external solution switching and the switching of the pipet solution during recording, to the loose patch, the perforated patch, and the patch cram detection technique. The advanced techniques covered combine molecular biology and imaging to produce the patch pipet with RT-PCR and fluorometric techniques.

Patch clamping is a widely applied electrophysiological technique for the study of ion channels; membrane proteins that regulate the flow of ions across cellular membranes and therefore influence the physiology of all cells. Patch Clamping aims to cover the basic principles and practical applications of this important technique. Starting with a review of the history of patch clamping, the text then goes on to cover the basic principles, platforms, equipment and environmental control, and will also include coverage of preparation types, recording modes and analysis of results. This book will explain the basic principles and practical application of patch clamp electrophysiology Written in a non-technical style to ensure its broad appeal to novice users Takes a practical approach This self-contained guide provides everything a practising patch clamp electrophysiologist needs to know to master this technique, including an overview of membrane biophysics, standard experimental design, data analysis, and technical concerns

Written by world experts in the field of neuronal chemoreception, Methods in Chemosensory Research describes new molecular, electrophysiological, genetic, behavioral, psychophysical, and imaging techniques that have recently been adapted to investigate the basic neuronal mechanisms underlying chemoreception: taste, olfaction and chemical-induced irritation. This unique book includes a wide variety of new and innovative imaging methods, electrophysiological methods, methods to investigate development, and various aspects of behavioral testing. Covering the entire spectrum of chemoreception, each section not only describes what information can be obtained by using each method, but also shows how to apply each method to obtain reliable results. The book presents a comprehensive view of how the brain uses information about chemical stimuli that interact with receptors in the nose and tongue. Methods in Chemosensory Research gives you the new tools to learn how chemicals affect activity from the genetic to the behavioral levels.
