General description

Tetraethylammonium (TEA), a simple quaternary ammonium compound, is commonly used to block potassium channels. It can physically enter the pore and block the channel. Additionally, TEA either imitates or antagonizes the actions of choline and acetylcholine, two other quaternary ammonium ions.

Application

Tetraethylammonium chloride has been used:

  • as a pharmacological agent in electrophysiology to study its pharmacological effects on Cnidarians
  • as a component in refolding buffer for protein refolding
  • to puff onto isolated patches to block voltage-gated K+ (Kv3) channels and post-hoc evaluation

Features and Benefits

  • Assay: ≥99.0% (AT), BioUltra, for molecular biology
  • Suitable for gas chromatography (GC)

OCTN1 was immuno-detected in the cervical cancer cell HeLa, in which the complete pattern of acetylcholine metabolizing enzymes is expressed. Comparison of immuno-staining intensity of HeLa OCTN1 with the purified recombinant human OCTN1 allowed measuring the specific OCTN1 concentration in
