α-Melanocyte stimulating hormone (α-MSH) is a pituitary hormone that plays a key role in appetite control and the skins UV protection and development of pigmentation. Also has effects on energy homeostasis, sexual activity, and as an anti-inflammatory. Potent agonist of the melanocortin receptors MC1, MC3, MC4, and MC5 (Ki=0.12, 31, 660, and 5700 nM, respectively), but not MC2. These highly purified, pre-validated control ligands have been used to qualify our InCELL Hunter, PathHunter and cAMP Hunter cell lines as well as our Assay Ready Kits. Ligands are conveniently supplied with a recommended reconstitution buffer. For detailed information and product-specific datasheet, visit www.discoverx.com/ligands.
