Overview
Patch clamp techniques are an electrophysiology tool used to measure the electrophysiological properties of a cell. The technique is based on the application of an electrical potential across a patch or membrane of a cell that is held in place using a micropipette. This allows researchers to measure the ion flux inside and outside of the cell, as well as measure changes in cell shape and electrical activity. Because of its sensitivity, patch clamp techniques are used to study a variety of conditions, such as ion channel function, cardiac arrhythmias, and neurodegenerative diseases. Additionally, patch clamp techniques can be used to assess the effects of drugs, toxins, and other environmental exposures on cell physiology. The technique is useful in helping researchers understand the detailed physiology of cells, allowing them to develop better treatments and therapies.
