MT-1

MT-1 is a Melanotan I supplied for laboratory research. Linear alpha-MSH analogue studied in vitro for melanocortin-1 receptor activation pathway modeling, photoprotective signaling mechanism analysis, and pigmentation response research.

Melanotan I (afamelanotide) is a linear alpha-MSH analogue selective for the MC1 receptor, whereas Melanotan II is a cyclic, less-selective analogue that also acts on other melanocortin receptors. MT-1 is the more receptor-selective of the two.

MT-1 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-1 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-1 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.
