MT-2 (Melanotan II Acetate) 10mg

MT-2 (Melanotan II Acetate) 10mg — synthetic melanocortin research peptide

Melanotan II is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts as a non-selective agonist across several melanocortin receptors (MC1R, MC3R, MC4R, and MC5R), which makes it a broad reference compound in melanocortin signaling research.

Why MT-2 is used as a reference compound

Melanotan II's activity across multiple melanocortin receptor subtypes makes it a useful positive control and a comparator for more selective compounds such as PT-141.

Preclinical research areas

• MC1R signaling and melanogenesis pathways in melanocyte cell culture
• MC3R and MC4R signaling in animal models
• Receptor-selectivity comparisons with α-MSH and PT-141
• Downstream cAMP signaling in receptor-expressing cell lines

Handling and storage

• Store the sealed lyophilized vial at or below −18 °C, protected from light and moisture
• Reconstitute with bacteriostatic water or sterile water per your laboratory SOP
• After reconstitution, refrigerate at 2–8 °C and aliquot to limit freeze-thaw cycles
• Record lot number, reconstitution date, and solvent for reproducibility
• See the full SBR Labs handling & storage reference
