Descrizione generale

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.

Applicazioni

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

Caratteristiche e vantaggi

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

The open state of voltage-gated potassium (Kv) channels is associated with an increased stability relative to the pre-open closed states and is reflected by a slowing of OFF gating currents after channel opening. The basis for this stabilization is usually
