Abstract
This unit describes general methodologies for the characterization of ATP-sensitive K+ channels and the study of ligand-channel interactions in native tissues and clonal cell lines by electrophysiological techniques. Detailed protocols on how to establish patch-clamp single-channel and whole-cell current recording are presented. Two-electrode voltage clamp techniques for studying ATP-sensitive K+ channels expressed in Xenopus oocytes are also included.
