In research, MT2 is studied for its non-selective binding to MC1R, MC3R, and MC4R and the resulting effects on pigmentation, appetite, and sexual signaling.\u003c\/p\u003e\n\u003cp\u003eThe MT2 lyophilized product is produced to high-quality standards and verified by HPLC to a purity of ≥ 99%.\u003c\/p\u003e\n\u003ch2\u003eSpecification Table\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSample\u003c\/td\u003e\n\u003ctd\u003eMT2 (Melanotan II)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAS Number\u003c\/td\u003e\n\u003ctd\u003e121062-08-6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePurity\u003c\/td\u003e\n\u003ctd\u003e± 99+ % (HPLC – COA available)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolecular Formula \/ Weight\u003c\/td\u003e\n\u003ctd\u003eC₅₀H₆₉N₁₅O₉ \/ 1024.18 Da\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSequence\u003c\/td\u003e\n\u003ctd\u003eAc-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalysis Lab\u003c\/td\u003e\n\u003ctd\u003eJanoshik Independent Peptide Analytics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eForm\u003c\/td\u003e\n\u003ctd\u003eLyophilized product (dry powder)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Conditions\u003c\/td\u003e\n\u003ctd\u003eStore refrigerated, protected from light and moisture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResearch Relevance\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-receptor melanocortin research\u003c\/strong\u003e — activates MC1R, MC3R, and MC4R simultaneously.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMC1R pigmentation\u003c\/strong\u003e — classical model for eumelanin stimulation and skin pigment research.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMC3R\/MC4R signaling\u003c\/strong\u003e — models around central appetite and sexual activation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComparison with PT-141\u003c\/strong\u003e — PT-141 is more selective for MC3R\/MC4R; MT2 also activates MC1R.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIndependently tested by Janoshik Independent Peptide Analytics for purity, heavy metals, and endotoxins.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is MT2?\u003c\/strong\u003e\u003cbr\u003eMT2 is a synthetic cyclic peptide developed by Hadley and Hruby at the University of Arizona in 1989. Its cyclic structure (lactam bridge between Asp and Lys) significantly increases stability and receptor affinity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does MT2 differ from MT1?\u003c\/strong\u003e\u003cbr\u003eMT2 is cyclic and non-selective (MC1R, MC3R, MC4R), while MT1 is linear and more selective for MC1R. As a result, MT2 has a broader mechanistic research scope but less targeted signaling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat purity is guaranteed?\u003c\/strong\u003e\u003cbr\u003eJanoshik validates each batch for HPLC purity ≥ 99%, with additional analysis of heavy metals and endotoxins.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is MT2 stored?\u003c\/strong\u003e\u003cbr\u003eStore the lyophilized product refrigerated (2–8 °C), protected from light and moisture.
