Description

PE 22-28

Introduction

PE 22-28 is a synthetic heptapeptide derived from spadin and is primarily investigated in laboratory and preclinical research. It has been studied for its interaction with the TREK-1 (TWIK-related potassium channel-1), a potassium channel involved in neuronal signaling. PE 22-28 is considered an investigational compound and is not approved as a therapeutic medicine in many jurisdictions.

Research-grade PE 22-28 is manufactured using controlled peptide synthesis and advanced purification processes designed to support product identity, purity, and batch consistency.
