Sortilin-derived neuropeptide for TREK-1 channel research
Research Compound
Manufactured under strict quality control protocols with full analytical testing. Certificate of Analysis (COA) available upon request.

PE-228 (also referenced in the literature as PE 22-28) is a short sortilin-derived peptide studied as a TREK-1 potassium channel inhibitor. The TREK-1 pathway has been linked to mood regulation and neuronal excitability, making PE-228 a research tool in neuropharmacology and antidepressant-mechanism studies.

Scientific Documentation
Detailed research information, pharmacological profile, and handling specifications
PE-228 is derived from the propeptide of sortilin and inhibits the TREK-1 (KCNK2) two-pore-domain potassium channel. TREK-1 inhibition in cortical and serotonergic circuits has been linked to fast-onset antidepressant-like effects in rodent models, paralleling the mechanism initially identified with the parent peptide spadin.
