Patch-Clamp Applications and Protocols presents the broadest coverage of techniques for measuring and recording directly activity within a cell. The first part of the book offers modern developments associated with the technology of path-clamp electrodes, of cell-free ion-channel recording, and of the whole-cell patch clamp technique. Chapters on such recent offspring of the technique as the concentration clamp technique, the pressure clap method, and the perfusion of patch clamp electrodes are contributed by authors intimately involved with their development. Also covered is the loose patch-clamp technique, single-channel recording, the perforated patch-clamp technique, molecular biological aspects of the technique, and the use of the technique in brain slices. Every scientist working with path-clamp methods will find this protocols manual invaluable to their continued use and development of this powerful technique.
