You've probably been burned by peptides that degrade before you can run meaningful assays, and that's where this one holds up—lyophilized powder sealed under inert gas, stable for 24 months if you keep it at -20°C and away form light.
It's a synthetic analog of α-MSH, CAS 121062-08-6, with a molecular weight of 1024.2 g/mol and purity over 99% by HPLC, so you're not chasing impurities through your melanogenesis or metabolic studies.
sequence—Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2—gives it a tighter binding profile than some older analogs, but don't expect it to work for appetite suppression in every model; we've seen variability depending on teh strain.
Most buyers go with the standdard 10mg vials, but we can do custom fill sizes if your protocol calls for something different—just check lead time on that (usually 2-4 weeks).
Solubility in water is straightforward, but it's not suited for long-term storage at room temp; even a few days above -20°C can knock stability down to about 6 months or so.
We usually have stock on the 10mg format, but confirm lead time for bulk orders—MOQ is 10 vials, and we'll include the COA with each batch.
Our standard MOQ is 1 gram, but we can accommodate smaller research quantities if you reach out directly.
Lead time is typically 5-7 business days for in-stock items, though international orders may take up to 14 days depending on customs.
Yes, each batch comes with a COA confirming >99% purity by HPLC, along with the peptide sequence and other quality specs.
Store it at -20°C in a sealed vial protected from light—just keep it out of direct sunlight and freeze-thaw cycles.
We offer custom packaging and labeling for bulk research orders, including private labeling if you need it—just let us know your requirements.
