Description
In preclinical research, Melanotan I (afamelanotide) is studied for its role in melanogenesis, melanocortin receptor pharmacology, photoprotection, and neuroendocrine signalling. Researchers use it to investigate MC1R-mediated pathway activation and receptor-specific signal propagation at molecular and cellular resolution.
Supplied as a sterile white lyophilised powder.
