MT-2 is a synthetic cyclic melanocortin analogue used in receptor research.\u003c\/p\u003e\n\u003cp\u003eMT-2 is a cyclic peptide, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH, at 1025.2. The square brackets in that notation mark the ring: a bond joins two side chains, closing part of the backbone into a loop rather than leaving it as an open chain.\u003c\/p\u003e\n\u003cp\u003eConstraining a peptide into a ring restricts the shapes it can adopt. For receptor research that is valuable, because a molecule locked into fewer conformations gives more interpretable binding data than a flexible chain that samples many.\u003c\/p\u003e\n\u003cp\u003eIt binds across several melanocortin receptor subtypes rather than selecting sharply between them, which is precisely why it is used as a broad reference compound in the field.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMelanocortin receptor subtype binding assays\u003c\/li\u003e\n\u003cli\u003eCyclic peptide conformational restriction research\u003c\/li\u003e\n\u003cli\u003eReference-compound use in receptor panels\u003c\/li\u003e\n\u003cli\u003eMelanogenesis pathway models in cell culture\u003c\/li\u003e\n\u003cli\u003eComparative work against linear alpha-MSH fragments\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 lyophilized powder in a sealed research vial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize available:\u003c\/strong\u003e 10mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 vial, 3 vials, or 10 pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula:\u003c\/strong\u003e C50H69N15O9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight:\u003c\/strong\u003e 1025.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence:\u003c\/strong\u003e Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOther MT-2 formats and related analogues\u003c\/h2\u003e\n\u003cp\u003eThe same analogue is stocked as a \u003ca href=\"\/products\/melanotan-2-nasal-spray\"\u003eMelanotan 2 nasal spray\u003c\/a\u003e.
