| Bioactivity | Proadrenomedullin (N-20) (ProADM N20) (bovine, porcine) is a potent and noncompetitive hypotensive and catecholamine release-inhibitory peptide released from chromaffin cells. Proadrenomedullin (N-20) (bovine, porcine) inhibits catecholamine secretion with an IC50 of 350 nM in PC12 pheochromocytoma cells. Proadrenomedullin (N-20) (bovine, porcine) also blocks (EC50≈270 nM) nicotinic cholinergic agonist desensitization of catecholamine release, as well as desensitization of nicotinic signal transduction (22Na+ uptake)[1]. |
