Atrial natriuretic peptide (ANP) (3-28) is a synthetic and truncated form of ANP, which is an endogenous peptide generated by proteolysis of prepro-ANP that is secreted by cardiomyocytes in the heart.1,2,3 ANP (3-28) potently inhibits renin release from cultured renal juxtaglomerular cells (Ki = 10 pM) in a cGMP-dependent manner.4 It also dose-dependently decreases mean arterial pressure (MAP) and arterial plasma renin activity and increases fractional sodium and calcium excretion, urine volume, and glomerular filtration rate in conscious dogs with a maximum effect attained when administered at a dose of 200 pM.5 ANP (3-28) (human) is a 26 amino acid peptide corresponding to the truncated human protein sequence.WARNING This product is not for human or veterinary use.
