Conventional micropipette-based patch clamp techniques

Abstract

The patch clamp technique revolutionized the study of ion channels and is considered the gold standard of measuring ion channel activity, from the academic laboratory to industrial-scale drug screening. This technique enables the study of ion channels, from single molecules up to the whole-cell ion channel population, and in their native environment. Whilst the study of single protein molecular behavior is the ultimate goal of biophysicists from all fields, this is a routine ability for ion channel specialists. This chapter is aimed at helping the beginner to design patch clamp experiments and to obtain the fundamental micropipette configurations with mammalian cells: cell-attached patch, whole cell, inside-out patch, and outside-out patch. © 2013 Springer Science+Business Media, LLC.
