Dermorphin is a naturally occurring opioid heptapeptide isolated from amphibian skin that acts with high potency and selectivity at mu opioid receptors. Its D-amino-acid configuration confers resistance to degradation, and investigators use it as a reference mu-agonist in receptor-binding, analgesia and opioid-pharmacology research. In opioid-receptor research, this heptapeptide is typically the reference mu-agonist in binding and analgesia assays, where its D-amino-acid backbone is the feature compared against synthetic opioids, and investigators measure receptor selectivity and functional potency. Fresh dilutions are prepared per condition, and the lyophilized format keeps dosing reproducible. Our records verify purity, and matched vials are available for comparative panels. Shipments of Dermorphin include the batch record and reconstitution notes, and the heptapeptide reconstitutes for binding and analgesia assays. Comparative opioid panels can use matched vials from one lot, with packing matched to the shipping route. Trial and bulk quantities are available, with storage guidance included. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
