Potential Applications in Research (RUO)
Strictly for laboratory research. No health, diagnostic, or therapeutic claims.
- Melanocortin receptor pharmacology — quantify potency/efficacy at human MC1R/MC3R/MC4R using cAMP reporters or β‑arrestin recruitment in transiently or stably expressing cell lines.
- Ligand bias & signaling kinetics — compare MT‑1 vs. α‑MSH and other analogs across second‑messenger profiles (cAMP/IP, ERK phosphorylation) under serum‑defined conditions.
- Binding/competition assays — membranes or intact cells to determine Ki, association/dissociation rates, and rank‑order potency among melanocortin ligands.
- Photobiology/cellular pigmentation models — assess MITF/tyrosinase axis readouts and melanosome dynamics in melanocyte cultures (in‑vitro only) with standardized light/UV exposure paradigms.
- Analytical method development — RP‑HPLC/LC–MS(/MS) for identity, purity, recovery, and forced‑degradation stability across buffers and temperatures.

Quality, Storage & Handling
Each lot is confirmed by HPLC (purity) and MS (identity); the on‑vial QR links to the batch COA. Independent U.S. labs verify purity, quantity, and endotoxin.
- Storage (lyophilized): −20 °C long‑term or 2–8 °C short‑term; keep desiccated and protected from light.
- After reconstitution: Aliquot and store at ≤ −20 °C (or −80 °C per SOP); avoid repeated freeze–thaw cycles.
- Reconstitution tips: Use sterile water or suitable buffer; gently swirl/invert to dissolve. If sterility is required, 0.22 µm filter and aliquot promptly.
Shipping & Fulfillment
Ships with validated cold‑chain packaging. In‑stock orders placed before the daily cutoff ship the same day. 2‑Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included; international shipping available where permitted.
Compliance & RUO Disclaimer
For laboratory research only. Not a drug, cosmetic, food, or household chemical. Not for human or animal use, ingestion, diagnostic, or therapeutic applications. Purchasers warrant appropriate qualifications and compliance with applicable regulations and institutional policies.
FAQs
- Is MT‑1 the same as MT‑II?
- No. MT‑1 (Afamelanotide) is the 13‑mer NDP‑α‑MSH analog listed above. MT‑II (Bremelanotide/PT‑141) is a distinct cyclic heptapeptide.
- Do you provide a PubChem image?
- Yes—the 2D structure above is rendered from PubChem CID 16130945 for Afamelanotide (NDP‑α‑MSH).
- What purity do you provide?
- Each 10 mg vial is ≥99% by HPLC with MS identity confirmation; third‑party testing is performed on every lot (COA via on‑vial QR).
- How should I reconstitute it?
- Dissolve in sterile water or a compatible buffer; gently invert until fully dissolved. If your SOP requires sterility, 0.22 µm filter and aliquot to avoid repeat freeze–thaw.
