How it works
-
Receptor
Melanocortin Receptor Binding
Melanotan I is characterised as an α-MSH analog binding the melanocortin receptor family, with MC1R the principal studied target in pigmentation research.

Cellular
Melanogenesis Endpoints
Melanin synthesis in melanocyte culture is the standard measured endpoint in the published MC1R literature.

Structure
Linear vs Cyclic
Melanotan I is linear where Melanotan II is cyclic. The structural difference is associated with differing receptor-selectivity profiles across the melanocortin family.

Frequently asked questions
How does Melanotan I differ from Melanotan II?
Melanotan I is linear; Melanotan II is cyclic. The structural difference is associated with differing selectivity across the melanocortin receptor family. Both are studied in melanocortin research.
What is the principal studied target?
The melanocortin-1 receptor (MC1R), characterised in pigmentation research using melanocyte culture models.
Is a molecular weight listed?
The molecular weight will be published here from the lot's Certificate of Analysis rather than quoted from a secondary source.
What purity is documented?
Each lot is analysed by reverse-phase HPLC and released at ≥99%, with a Certificate of Analysis.
How is it stored?
Store lyophilized at -20°C for long-term stability, protected from light and moisture, and avoid repeated freeze-thaw cycles.
