Potassium Channels -

. .

Résumé :
Due to the importance of potassium channels in cellular function, researchers have been challenged to develop tools and experimental procedures to probe the function and identify chemicals that modulate the behaviour of this super-family of ion channels. In Potassium Channels: Methods and Protocols, experts in the field present a range of experimental approaches that have been developed to investigate potassium channel structure, function, pharmacology, cell biology, gene expression, and their role in disease. Many of these techniques study potassium channels as cellular proteins as well as the resultant membrane biophysics. Written in the highly successful Methods in Molecular Biology? series format, the chapters contain brief introductions to the subject, lists of the necessary materials and reagents, readily reproducible laboratory protocols, and a Notes section, which highlights tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, Potassium Channels: Methods and Protocols provides a wide range of approaches in order to aid current research projects and inspire new investigations.
