Overview
Receptor-targeted peptides bind specific G-protein-coupled or nuclear receptors to probe pharmacology in neuropsychiatric, dermatological, or sleep-related pathways.
Melanotan II is studied for its activity at MC1R / MC3R / MC4R / MC5R, with a reported half-life of ~30 min. The compound is supplied as a lyophilized powder and reconstituted with bac water prior to use in laboratory research.
Mechanism of Action
GPCR-mediated cAMP / Ca²⁺ signaling specific to the target receptor family.
In published in-vitro work, Melanotan II engages MC1R alongside related receptor subtypes to initiate downstream signaling. The reported half-life of ~30 min informs typical dosing intervals in experimental protocols.
Research Applications
- Receptor binding affinity assays
- Behavioral pharmacology in animal models
- Intranasal delivery and CNS penetration studies
- Comparative selectivity against close analogs
Handling & Reconstitution
Reference guidance for laboratory handling.
- Storage: -20°C lyophilized. Avoid repeated freeze-thaw cycles.
- Reconstitution: BAC water. Add diluent slowly down the side of the vial; gentle swirl, do not shake.
- Stability: Once reconstituted, store at 2–8°C and use within 14–28 days depending on peptide stability.
- Working solution: Calculate target concentration before reconstitution. Our calculator can help.
Quality & Verification
- Every batch of Melanotan II we ship is third-party tested by an ISO-accredited lab. Each order arrives with a batch-matched Certificate of Analysis showing HPLC purity (≥99%), mass spectrometry confirmation of 1024.2 Da, and endotoxin / bioburden screening where applicable.
