Description

Melanotan II – Pre-filled Laboratory Cartridge for In Vitro Research (10 mg / 3 ml)

Synthetic cyclic -MSH analogue and non-selective melanocortin receptor agonist (MC1R–MC5R) in a pre-formulated stabilized buffered solution for in vitro research on melanogenesis pathways, intracellular cAMP cascades, and receptor binding pharmacology

Overview & Mechanism of Action (In Vitro)

Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue derived from the endogenous melanocyte-stimulating hormone (-MSH). In cell biology, experimental dermatology, and molecular pharmacology, it serves as a primary reference standard for investigating melanocortin signaling networks and receptor selectivity across cultured cell models:

• Non-Selective Melanocortin Receptor Engagement (MC1R, MC3R, MC4R, MC5R): Displays high binding affinity across the G-protein-coupled receptor family (), facilitating comparative in vitro profiling of receptor kinetics and downstream signal transduction.
• Stimulation of the Adenylate Cyclase and cAMP Cascade: Triggers robust intracellular cyclic adenosine monophosphate () accumulation and subsequent protein kinase A (PKA) activation upon receptor engagement in experimental cell lines.
• Modulation of the Melanogenic Transcription Axis (MITF / Tyrosinase): In primary and cultured melanocyte models, it promotes microphthalmia-associated transcription factor (MITF) activation, upregulating tyrosinase enzyme expression and eumelanin synthesis in vitro.
• Pre-formulated Format for Precise Laboratory Dispensing: The stabilized liquid formulation within a 3 ml cartridge eliminates manual reconstitution variability, ensuring exceptional homogeneity and concentration consistency for automated and semi-automated micro-dispensing systems.
