Potassium Channel Related Research Reagents

Potassium Channels

Potassium ion channels are the most widely distributed type of ion channels and are found in almost all living organisms. They form potassium-selective pores across cell membranes. Potassium ion channels are present in most cell types and control a variety of cell functions such as cognition, muscle contraction and hormone secretion. Therefore, abnormal function of potassium channels may lead to diseases (such as diabetes) and life-threatening arrhythmias. Potassium channels may also be involved in maintaining vascular tone.

There are four main types of potassium channels:
