PE-22-28 is a synthetic peptide derived from Spadin, studied in neuropharmacology and potassium-channel research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. PE-22-28 is investigated in research on TREK-1 channel modulation and related neuronal signaling, and is commonly applied in cell-based and preclinical studies. The stable freeze-dried presentation supports convenient reconstitution and reproducible dosing. PE-22-28 is run in behavioral pharmacology where the design measures despair-like behavior and anxiety indices in rodent models, and investigators often compare its channel-targeting mechanism against conventional monoaminergic agents to see where the pharmacology differs. The defined sequence keeps synthesis reproducible, and the lyophilized material reconstitutes for consistent administration across treatment days. Our records verify purity per batch, and we can supply matched lots for multi-group designs, with delivery arranged within recommended conditions. Reconstitution follows the indicated dilution step, and the notes cover storage for the multi-day behavioral designs this peptide is used in. We can provide matched lots for multi-group comparisons and coordinate delivery within recommended handling conditions. Trial and bulk quantities are available, with packing that protects the powder during shipping. As a factory-connected supplier, we keep stable stock of popular peptides and can accommodate custom pack sizes, OEM labeling and private-label requests. Shipments are handled by experienced logistics partners with secure packing and reliable delivery timelines.
