Melanotan I Overview
Melanotan I is a synthetic peptide analog of the naturally occurring alpha-melanocyte-stimulating hormone (?-MSH). It is commonly studied for its interaction with melanocortin receptors, especially MC1R, which plays a role in pigment-related signaling pathways. This peptide is utilized in laboratory settings to explore receptor binding, signal transduction, and melanogenesis-related biochemical processes.
Product Details
Sequence: Ac-Nle-Asp-His-D-Phe-Arg-Trp-Lys-NH2
Molecular Formula: C78H111N21O19
Molecular Weight: 1646.88 g/mol
PubChem CID: 91751

Research Highlights
Melanocortin Receptor Binding: Melanotan I is frequently used to study the binding characteristics of melanocortin receptor subtype MC1R in vitro and in vivo models.
Signal Transduction Pathways: Investigations involving this peptide contribute to understanding intracellular signaling cascades triggered by ?-MSH analogs.
Melanogenesis Mechanisms: Utilized in controlled laboratory environments to model and analyze melanin production pathways and pigment biosynthesis.
Comparative Receptor Activity: Often used in comparative research alongside other melanocortin analogs to evaluate relative efficacy and receptor specificity.
Usage and Safety Information
This product is intended for research use only. It is not approved for human use, non-research applications, or cosmetic procedures. All experiments involving Melanotan I should comply with relevant safety and handling protocols.
