Description
PE-22-28 — Spadin-Derived Peptide Fragment
PE-22-28 is a seven-amino-acid derivative of the spadin peptide, supplied for in vitro laboratory research only.
Research context
Preclinical literature has examined PE-22-28 as a selective antagonist of the TREK-1 (K2P2.1) two-pore-domain potassium channel. Investigators use it in ion-channel electrophysiology assays, hippocampal cell-culture models, and rodent behavioural-pharmacology model systems examining BDNF expression and synaptic signalling downstream of channel blockade. Reported study designs include patch-clamp recordings characterising channel conductance, quantitative PCR and immunohistochemical analysis of hippocampal BDNF expression, and receptor-binding assays comparing selectivity against related two-pore-domain potassium channel subtypes. As a shortened spadin derivative, PE-22-28 is also referenced in comparative ion-channel pharmacology literature alongside related two-pore-domain potassium channel ligands, with additional study designs pairing chromatographic stability analysis with gene-expression profiling of hippocampal synaptic-plasticity markers across multiple rodent brain-slice preparations.
