<H4text="Principles of the patch clamp technique"></H4>
<p>Patch clamp recording involves the use of a glass micropipette which is manufactured from a glass capillary through the use of a Micropipette Puller. The micropipette is then filled with an electrolyte solution, which is subsequently brought into contact with the cell membrane. By applying gentle suction, a high-resistance seal called giga seal is formed between the pipette tip and the membrane patch. This enables the measurement of ionic currents with minimal noise interference [3]. <strong>Whole-Cell Configuration</strong> records currents from the entire cell by rupturing the membrane patch, accessing the intracellular environment, and is useful for analysing overall ion channel activity and cellular responses. <strong>Single-Channel Recording</strong> measures currents through individual ion channels without rupturing the membrane, enabling high-resolution study of channel conductance, gating, and selectivity [2].</p>
