Product Detail

Melanotan I Full Detailed Product Description

Product Overview

Melanotan I is a synthetic cyclic peptide analogue of alpha-melanocyte stimulating hormone (α-MSH). It is a laboratory-grade lyophilized peptide designed for research focusing on melanogenesis, skin pigmentation and melanocyte biological studies. Compared with Melanotan II, MT-1 delivers more targeted pigmentation effects with weaker systemic secondary reactions, making it a preferred research material for skin melanin related experiments.

Basic Product Specifications

Full Name: Melanotan I
Sequence: Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2
Molecular Formula: C78H111N21O19S
Molecular Weight: 1646.9 Da
Purity: ≥99% (HPLC & Mass Spectrometry verified)
Appearance: White sterile lyophilized powder
Solubility: Easily soluble in bacteriostatic water and distilled water
Standard Package: 5mg / 10mg sterile sealed vials
Quality Documents: COA, HPLC chromatogram, MS identification report supplied for every batch
Shelf Life: 24 months under proper storage
Storage Condition: Long-term storage at -20°C, sealed, away from light and moisture; avoid repeated freeze-thaw cycles. Reconstituted solution can be stored at 2–8°C for up to 7 days.

Mechanism of Action

Melanotan I selectively binds to melanocortin 1 receptors (MC1R) expressed on melanocyte cell membranes. After receptor activation, signaling pathways including cAMP are upregulated, which further stimulates the activity of tyrosinase, the core rate-limiting enzyme for melanin synthesis.

It effectively promotes melanin production and deposition in epidermal melanocytes, inducing natural skin darkening and pigmentation. Unlike Melanotan II, MT-1 has low binding affinity with MC3, MC4 and MC5 receptors, so it barely triggers appetite, libido or cardiovascular side effects in research models.

Core Research Applications

Melanogenesis and melanocyte cell culture research
Pigmentation mechanism, UV radiation skin protection related experiments
Comparative study of different melanocortin receptor agonists
Cosmetic raw material development for tanning research
Skin damage repair and antioxidant preclinical testing
MC1R gene expression and signal transduction research

Product Advantages

Ultra-high purity over 99%, low impurity content, stable activity between batches
Targeted MC1R activation with minimal off-target receptor stimulation
Good water solubility, dissolves completely without residue after reconstitution
Strict sterile freeze-drying process, low endotoxin level suitable for cell
Complete traceable test reports to support third-party laboratory inspection

Important Disclaimer

This product is for laboratory research use only. It is not approved for human oral intake, cosmetic production, clinical treatment or personal tanning use. All related data are limited to in vitro cell and animal model experiments. Handle this peptide in strict accordance with laboratory safety operating standards.

Short Bullet Points for Listing Page

Research

Class:

Mitochondrial-derived peptide (MDP), 16-amino-acid peptide

Status:

Research compound — Not FDA approved

Mechanism:

MOTS-c (mitochondrial ORF of the twelve S rRNA-c) is a 16-amino-acid peptide encoded by the mitochondrial genome (not nuclear DNA). It is a mitochondrial-derived peptide that regulates metabolic homeostasis by activating the AMPK/PGC-1\u03b1 pathway, improving insulin sensitivity, and enhancing exercise capacity. MOTS-c crosses the blood-brain barrier and has been shown to reduce body weight and improve glucose tolerance in preclinical models.

Activity note:

MOTS-c does not act via a traditional receptor. It functions as a metabolic regulator, activating AMPK. Functional effects are observed at micromolar concentrations in cell-based assays.
