About MT-2
Melanotan II (MT-2) is a cyclic synthetic heptapeptide analog of α-MSH incorporating a lactam bridge between aspartic acid and lysine residues to constrain the peptide backbone into a pharmacologically active β-turn conformation. The molecule features an N-terminal norleucine residue for stability, a D-Phe residue at position 4 for enhanced MC receptor affinity (the His-D-Phe-Arg-Trp core constitutes the essential melanocortin pharmacophore), and a C-terminal hydroxyl rather than the amide found in bremelanotide (PT-141). MT-2 acts as a non-selective agonist across melanocortin receptor subtypes MC1R, MC3R, MC4R, and MC5R.
Research applications of MT-2 include melanocortin receptor binding competition assays, comparative receptor selectivity studies relative to α-MSH and linear analogs, cAMP signaling pathway characterization in transfected cell lines, and investigation of MC4R activation dynamics in hypothalamic neuronal cell models. The rigid cyclic structure of MT-2 makes it a valuable tool in structure-activity relationship studies examining the conformational requirements of the melanocortin pharmacophore. For laboratory research use by qualified investigators only.

Lyophilized Research Peptides
This product is supplied in lyophilized (freeze-dried) form — a process that extends shelf life and preserves peptide purity and structural integrity during storage. No fillers, excipients, or preservatives are used in the lyophilization process. The lyophilized powder should be reconstituted with an appropriate research-grade solvent in a controlled laboratory environment prior to use in in vitro or preclinical assay systems.
