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.

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.

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.

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.

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.
