Techniques for studying ion channels: an introduction.
In this Introduction to the Special Issue on Ion Channels in Plants, the techniques used to study ion channels are reviewed. In particular, the basic approaches used for the electrophysiological study of ion channels are explained, from voltage clamping membranes and observing current changes over time, to the construction of current-voltage relations and the use of tail current protocols to determine channel selectivity. This is done for whole-cell and single channel records.
