Description
Melanotan I is an alpha-MSH analogue studied for melanocortin-1 receptor activity. Compared with Melanotan II it is the more receptor-selective of the pair, which is why it appears in pigmentation-specific work.
Research context
- MC1 receptor and melanogenesis studies
- Photoprotection models
- Comparative work against Melanotan II
Handling and storage
Store cold and protected from light; reconstituted solution refrigerated.
Common questions
How does it differ from Melanotan II?
