- Scientific name
- Acetyl-[Nle4, Asp5, D-Phe7, Lys10]-cyclo-α-MSH(4–10) amide (melanotan-II, MT-II)
- Amino acids
- 7
- Sequence
- Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-NH2
- Molecular weight
- 1024.2 g/mol
- Formula
- C50H69N15O9
- CAS
- 121062-08-6
- Origin
- Synthetic cyclic lactam heptapeptide analogue of α-MSH residues 4–10, designed at the University of Arizona (Al-Obeidi/Hruby, 1989); the Asp5–Lys10 lactam bridge forms a 23-membered ring.
- Lyophilized (powder)
- -20°C · stable long-term; keep sealed, desiccated and protected from light
- Reconstituted
- 2-8°C · use within 30 days; avoid repeated freeze-thaw cycles
- Room temperature
- Lyophilized powder tolerates short shipping excursions of a few days, but peptide in solution degrades within days at room temperature — reconstituted vials should not be held above 8°C.
