Melanotan 2 is a synthetic cyclic analogue of alpha-melanocyte-stimulating hormone studied in melanocortin receptor research.\u003c\/p\u003e\n\u003cp\u003eMelanotan 2 is a cyclic peptide, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH, with a molecular weight of 1025.2. The ring structure is the defining feature: closing the backbone into a ring constrains its shape and slows enzymatic breakdown compared with the linear hormone fragment it is modelled on.\u003c\/p\u003e\n\u003cp\u003eBecause it is shorter and more stable than natural alpha-MSH, it is widely used as a reference compound in melanocortin receptor binding studies, where a consistent, well-characterised analogue is more practical than the parent hormone.\u003c\/p\u003e\n\u003cp\u003eIts stability relative to the natural hormone is the practical reason it appears so often in receptor work. A compound that persists through an assay gives cleaner comparative data than one degrading over the same period.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMelanocortin receptor binding and selectivity assays\u003c\/li\u003e\n\u003cli\u003eCyclic peptide conformation and stability research\u003c\/li\u003e\n\u003cli\u003eMelanogenesis pathway models in cell culture\u003c\/li\u003e\n\u003cli\u003eComparative studies against linear alpha-MSH fragments\u003c\/li\u003e\n\u003cli\u003eStructure-activity work across melanocortin analogues\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e pre-prepared liquid in a research spray bottle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize available:\u003c\/strong\u003e 10mg (166mcg\/spray)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 spray bottle, 3 spray bottles, or 5 spray bottles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOther Melanotan formats and related research peptides\u003c\/h2\u003e\n\u003cp\u003eThe same analogue is stocked as the \u003ca href=\"\/products\/melanotan-ii-mt-2\"\u003eMT-2 lyophilized vial\u003c\/a\u003e.
