Dermorphin is a naturally occurring opioid heptapeptide derived from amphibian skin, studied in neuropeptide and opioid-receptor research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Dermorphin is investigated in research on opioid receptor signaling and pain pathways, and is commonly applied in cell-based and preclinical studies. The lyophilized format provides high stability and easy reconstitution for consistent experimental dosing.. Every manufacturing run is QC-checked and batch-specific analysis reports are provided on request. Unopened vials should be kept sealed at 2-8 degree C away from light and moisture, and for longer-term storage -20 degree C is advised while minimizing freeze-thaw exposure. We welcome both sample orders and large quantities, and offer OEM, private-label and secure neutral packing for international shipping. For laboratory research use only.
