MT-2

Melanotan II

MT-2 (Melanotan II) is a cyclic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH) with broad, potent activity across multiple melanocortin receptors, including MC1R, MC3R, and MC4R. Its wider receptor engagement is the key distinction from the more MC1R-selective MT-1.

In vitro and preclinical studies examine melanocortin-receptor activation, melanogenesis and pigmentation signaling, and MC4R-linked energy-homeostasis and appetite pathways, the MC4R activity being a research area unique to the broader melanocortin agonists. Its cyclic structure and multi-receptor profile are frequent subjects of characterization work. Supplied as a lyophilized 10-vial 10mg kit for in vitro research use only.

Common Questions

MT-2 FAQ

What is MT-2?+
MT-2 is a Melanotan II supplied for laboratory research. Alpha-MSH analogue studied in vitro for melanocortin receptor activation pathway modeling, pigmentation signaling analysis, and energy homeostasis mechanism research.
What is the difference between Melanotan 2 and Melanotan 1?+
Melanotan II is a cyclic, non-selective alpha-MSH analogue acting across multiple melanocortin receptors, while Melanotan I (afamelanotide) is linear and MC1-selective. MT-2’s broader receptor activity is a focus of melanocortin research.
What is lyophilized MT-2, and how is it reconstituted?+
MT-2 is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should MT-2 be stored?+
Store the lyophilized MT-2 powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of MT-2, and how is it tested?+
Every batch of MT-2 is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
