Patch clamp techniques for single channel and whole-cell recording
The patch clamp technique was first used by Neher and Sakmann (1976) to resolve currents through single acetylcholine-activated channels in cell-attached patches of membrane of frog skeletal muscle. The method they used (described by Neher, Sakmann & Steinbach, 1978) and subsequent refinements (Hamill, Marty, Neher, Sakmann & Sigworth, 1981) have led to techniques for high resolution recording ...
متن کاملWhole-Cell Patch-Clamp Recordings
The patch-clamp recording technique, which measures ionic currents under voltage clamp, was designed to study small patches of membranes in which near perfect control of the transmembrane voltage can be achieved readily. The recent application of patch-clamp methodology to the analysis of whole-cell current actually defies many of the original design requirements. Nevertheless, whole-cell recor...
متن کاملMechanosensitive ion channels investigated simultaneously by scanning probe microscopy and patch clamp.
Mechanosensitive ion channels play an important role for the perception of mechanical signals such as touch, balance, or sound. Here, a new experimental strategy is presented providing well-defined access to single mechanosensitive ion channels in living cells. As a representative example, the investigation of mechanosensitive transduction channels in cochlear hair cells is discussed in detail ...
متن کاملOne-channel cell-attached patch-clamp recording.
Ion channel proteins are universal devices for fast communication across biological membranes. The temporal signature of the ionic flux they generate depends on properties intrinsic to each channel protein as well as the mechanism by which it is generated and controlled and represents an important area of current research. Information about the operational dynamics of ion channel proteins can b...
متن کاملPatch and Whole-Cell Recording
Last time we considered at some length the sources of random noise due to the thermal motion of ions and electrons. Now we turn to the practical matter of dealing with the pickup of nonrandom electrical signals, such as interference from the 60 Hz power lines or from a computer monitor. There are two main principles to consider: electrostatic pickup through unshielded surfaces, and magnetic pic...
