Melanocortin analog
Melanotan-2
Melanotan-2 is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone, cyclized through a lactam bridge. In preclinical models, it binds to several melanocortin receptors, including MC1R, MC3R and MC4R, with a nonselective profile. It has been investigated in models of melanocortin signaling in rodent studies.

Shipping termsResearch context & mechanism
Cyclization restricts the peptide's conformation and modifies its relative affinity for receptor subtypes. All of these are Gs protein-coupled receptors in cellular models.

Batch documentation
Review documentation for the product and variant you are purchasing. A reference specification, a research publication and an individual batch certificate are different sources. Certificate results are accessed with your order details; if documentation is available on request, contact support before relying on it.
Consult batch certificates How to read documentationLaboratory handling
- Reconstitution
- Laboratory procedure: allow the closed vial to reach room temperature, disinfect the septum and slowly transfer the diluent against the inner wall of the vial. Do not shake; gently swirl the vial until fully dissolved. Record the volume, diluent and date in the batch log.
- Storage
- Sealed vial of lyophilized material: store at −20 °C, protected from light and moisture. Avoid repeated freeze-thaw cycles of reconstituted material; aliquot when the experimental design permits.
- Protective equipment
- Handle in a clean work area with a lab coat, nitrile gloves and eye protection. Dispose of vials, tips and sharps according to the laboratory waste procedure.
