Overview of Melanotan 1 in Preclinical Research
Melanotan 1 (also designated as MT-1 or Afamelanotide) is a synthetic peptide analog of endogenous alpha-melanocyte-stimulating hormone (alpha-MSH). Researched for melanocortin activity related to skin pigmentation responses, the molecule acts as a non-selective agonist across multiple melanocortin receptor subtypes, including MC1R, MC3R, MC4R, and MC5R. In preclinical cell culture assays and animal models, investigators utilize MT-1 to measure intracellular cyclic adenosine monophosphate (cAMP) accumulation and downstream enzymatic cascades involved in eumelanin synthesis.
When evaluating synthetic melanocortin signaling pathways, researchers frequently compare Melanotan 1 against structural or functional analogs. For instance, Melanotan 2 incorporates a cyclic core structure that yields distinct receptor binding kinetics and broader central melanocortin activation, while Bremelanotide (PT-141) is primarily studied for central neuroreceptor pathways rather than peripheral cutaneous responses. Investigators seeking to benchmark synthetic analogs across receptor panels can explore our complete catalog of research peptides for complementary experimental tools.
Analytical Verification and COA Standards
Ensuring experimental reproducibility requires rigorous analytical verification of every research peptide lot. PX1 Research subjects all production batches to High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) testing within ISO 17025 accredited laboratories. This process verifies primary amino acid sequence alignment, detects trace synthetic impurities, and guarantees peptide purity equal to or exceeding 99%.
To maintain full transparency, lot-specific testing documentation is publicly accessible via our certificate of analysis hub. Every shipment is labeled with a distinct lot identifier, allowing research teams to audit raw chromatographic data, mass spectra, and endotoxin assay results prior to initiating in vitro or preclinical protocols.
Reconstitution Standards and Storage Protocols
Proper handling and solvent selection are critical for maintaining peptide structural stability following receipt. Melanotan 1 is supplied as a lyophilized powder sealed under inert gas to prevent oxidative degradation. When preparing solutions for laboratory assays, investigators should utilize sterile bacteriostatic water or buffered aqueous diluents, taking care to minimize shear stress during mixing.
To streamline assay preparation and eliminate concentration errors, laboratory personnel can utilize our interactive reconstitution calculator. High-grade preparations such as the Melanotan 1 10mg vial should be stored frozen at -20°C in lyophilized form, while reconstituted liquid aliquots require strict refrigeration at 2°C to 8°C or deep freezing at -80°C for extended experimental series.

What is Melanotan 1?
Melanotan 1 is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH). In laboratory settings, it is classified as a non-selective melanocortin receptor agonist. It is supplied exclusively as a lyophilized powder for in vitro assay systems and preclinical animal models evaluating peptide-receptor interactions.
What is the primary focus of Melanotan 1 research?
Preclinical literature documents Melanotan 1 as a research compound studied primarily for melanocortin activity related to skin pigmentation responses. Researchers investigate its binding affinity across MC1R, MC3R, MC4R, and MC5R targets to observe signal transduction, eumelanin synthesis pathways, and cellular photoprotective mechanisms in epidermal cell cultures.
How is Melanotan 1 purity verified?
PX1 Research verifies Melanotan 1 purity using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). Each batch undergoes analytical testing in ISO 17025 accredited facilities to confirm chemical identity, sequence integrity, and a minimum purity threshold of 99%, ensuring consistency for laboratory experimental protocols.
How do I access the Certificate of Analysis (COA) for a lot?
Researchers can inspect batch-specific test results directly through our [certificate of analysis hub](/coa). Every shipment includes a lot number matching the digital COA, displaying raw HPLC chromatograms, mass spectral mass-to-charge verification, and quantitative purity data generated by independent analytical testing laboratories.
What are the storage requirements for lyophilized Melanotan 1?
Lyophilized Melanotan 1 powder should be stored in a freezer at -20°C or below, protected from light and moisture exposure. Desiccant containers are recommended to prevent humidity degradation. Under these controlled sub-zero conditions, unopened solid peptide samples remain chemically stable for up to 24 months.
How should reconstituted Melanotan 1 solutions be stored in the lab?
Once reconstituted into aqueous solution, Melanotan 1 must be refrigerated at 2°C to 8°C and evaluated within 30 days to prevent peptide hydrolytic degradation. For extended experimental timelines, aliquoting the solution into sterile polypropylene vials and storing at -80°C avoids repeated freeze-thaw cycles that disrupt peptide stability.
What is the recommended solvent for reconstituting Melanotan 1?
Bacteriostatic water containing 0.9% benzyl alcohol or sterile research-grade phosphate-buffered saline (PBS) is standard for reconstituting Melanotan 1 in laboratory assays. Diluents should be added slowly down the internal glass wall of the vial to minimize mechanical agitation and shear stress on the peptide matrix.
How do researchers calculate reconstitution volumes for precise concentration?
Laboratory technicians utilize our specialized [reconstitution calculator](/reconstitution-calculator) to determine precise diluent volumes required for target molar or milligram concentrations. Inputting the vial mass and desired concentration yields exact microliter addition volumes, eliminating manual calculation errors prior to cell culture or assay preparation.
How does Melanotan 1 differ from Melanotan 2 in receptor affinity studies?
Melanotan 1 exhibits higher selectivity for the melanocortin-1 receptor (MC1R) compared to [Melanotan 2](/research-peptides/melanotan-2), which possesses broader receptor activation across central nervous system targets. Unlike [Bremelanotide (PT-141)](/research-peptides/bremelanotide-pt-141), Melanotan 1 is evaluated primarily in cutaneous cell lines rather than central neuroreceptor pathway models.
What endotoxin testing standard is applied to PX1 research peptides?
PX1 Research enforces strict endotoxin screening using Limulus Amebocyte Lysate (LAL) assays on all production lots.
