Melanocortin analog
Melanotan-1
Melanotan-1 is a synthetic analog of alpha-melanocyte-stimulating hormone, with norleucine and D-phenylalanine substitutions described in the literature as determinants of its stability. NDP-alpha-MSH has been studied in in vitro melanocortin receptor binding assays and as a reference for comparing structural variants across subtypes. It has been studied in models of melanogenesis in in vitro studies.

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.
