PE 22-28 Powder CAS 1801959-12-5
Product Description
PE 22-28 Powder is a high-quality lyophilized research-grade peptide raw material synthesized via mature and standardized Fmoc solid-phase peptide synthesis (Fmoc-SPPS) technology. Composed of seven amino acids with a precise GVSWGLR sequence, this synthetic peptide is a structurally truncated derivative of the endogenous Spadin peptide. It is rationally optimized to retain potent TREK-1 inhibitory activity while achieving enhanced molecular structural stability and broader research applicability compared with the native Spadin peptide.
Functionally, PE 22-28 peptide selectively binds and interacts with neuronal TREK-1 two-pore domain potassium channels, serving as a highly specific and reliable molecular research tool for multiple neuroscience research directions. Presented as uniform white to off-white lyophilized powder, the product features stable and consistent HPLC-verified purity. It exhibits excellent solubility in common laboratory solvents, including purified water, PBS buffer and cell culture media, enabling convenient experimental preparation and stable performance for in vitro and preclinical research operations.
Product Application
1. Preclinical psychopharmacology research – Widely applied in preclinical studies related to neural regulation and psychopharmacological mechanism exploration.
2. Ion channel functional verification – Used for functional testing and mechanism analysis of neuronal potassium channel targets.
3. Spadin derivative comparative research – Suitable for contrast studies on structural optimization and activity differences of Spadin-series peptides.
4. In vitro neuronal experimental models – Stable soluble active for cell-level neural mechanism and ion channel research.
