Category overviewAbout this research category

Melanocortin peptides are studied for their activity at the melanocortin family of receptors. This category includes PT-141 (bremelanotide) and Melanotan II, supplied as reference materials for laboratory research into melanocortin-receptor signalling; 99%+ purity; batch COA; ships from Western Australia.

How melanocortin peptides are studied. The melanocortin system spans five receptor subtypes (MC1R–MC5R), and compounds in this class are characterised through receptor-selectivity assays, cAMP signalling and pigmentation-biology research in cell and animal models. Melanotan II is a cyclic synthetic analogue of alpha-MSH; PT-141 (bremelanotide) is a metabolite of Melanotan II studied at the MC3R and MC4R receptors; and the tripeptide KPV — the C-terminal fragment of alpha-MSH — connects this family to inflammatory-signalling research.

Where to start in this category. See What is Melanotan II?, What is PT-141? and What is KPV? for classification, mechanism research and the primary literature. Every batch is independently tested with a published Certificate of Analysis.
