Potassium Channel Research Reagents

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:

Calcium-activated potassium channels - open in response to the presence of calcium ions.
Inwardly rectifying potassium channels - pass current (positive charge) in the inward direction (into the cell).
Tandem pore domain potassium channels - constitutively open or have a high degree of basic activation, such as "quiescent potassium channels" or "leak channels" that set the negative membrane potential of neurons.
Voltage-gated potassium channels - voltage-gated ion channels that can open or close in response to changes in transmembrane voltage.
