Dermorphin
Dermorphin is a high-purity synthetic hepta-peptide originally discovered in the skin of South American frogs (Phyllomedusa genus). In the landscape of advanced neuroscience and molecular pharmacology, Dermorphin is distinguished by its extraordinary potency and high selectivity for the $\mu$-opioid receptor (MOR). Structurally unique due to the presence of a D-alanine residue in its second position—a rare natural occurrence of a D-amino acid in vertebrates—Dermorphin is significantly more potent than endogenous enkephalins and morphine. It provides researchers with a high-precision experimental model to investigate the mechanisms of antinociception (pain modulation), receptor internalisation, and the neurobiological pathways of the central and peripheral nervous systems.
Our Dermorphin is synthesized in an ISO 9001:2015 certified environment utilizing high-precision Solid-Phase Peptide Synthesis (SPPS). We achieve an ultra-high chemical purity of ≥99%, verified by HPLC and Mass Spectrometry (MS). This rigorous production standard ensures the peptide is free from truncated sequences and residual chemical catalysts, guaranteeing the consistency and structural fidelity required for high-stakes studies into opioid signaling and neuro-modulation.

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the Dermorphin powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and maintains the molecular stability of the hepta-peptide during storage.
High-Fidelity Sequence Integrity
Every batch undergoes strict Mass Spectrometry (MS) to confirm the specific D-Ala configuration, ensuring maximal receptor binding affinity and reproducible results in complex neuro-signaling assays.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the Dermorphin cake is at the base.
-
Solvent: Reconstitute with Sterile Water or PBS.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 10-14 days for optimal results.
