Anti-Brain Natriuretic Peptide Pro (proBNP, Natriuretic Peptides B, Gamma-brain Natriuretic Peptide,

Human BNP is a 3.5kD, secreted, nonglycosylated peptide that belongs to the natriuretic peptide family. It is the product of ventricular myocytes and bone marrow endothelial cells. BNP is synthesized as a 12kD, 108aa prohormone with a 76aa prosegment and a 32aa mature (BNP) region. Both forms circulate, with the prohormone showing O-linked glycosylation that generates a 25-27kD glycoprotein. Glycosylation is suggested to stabilize the molecule. The proform also tends to noncovalently trimerize. In blood, 1-32 BNP is proteolytically processed into 3-32 BNP, with loss of Ser-Pro at the N-terminus. Human Pro-BNP is 29% and 50% aa identical to mouse and pig Pro-BNP. Applications: Suitable for use in Western Blot. Other applications not tested.
