Patch Clamp Technique
The patch clamp technique is a widely used electrophysiological method for studying ion channels in cell membranes. This technique involves using a micropipette to form a gigaohm seal with a cell membrane, allowing for the manipulation of the electrical potential across the membrane. There are four main types of patch clamp, each with their own…

Ion Channels
Ion channels are vital membrane proteins that regulate the passage of ions, influencing cell physiology and essential processes like nerve impulses and muscle contraction. They can be categorized based on ion selectivity, gating mechanisms, and regulatory processes. Examples include voltage-gated channels that respond to membrane potential changes and ligand-gated channels activated by specific molecules. Cyclic…
