NT-proBNP (1-76) ELISA

Brain Natriuretic Peptide (BNP) is part of the Natriuretic Peptides family and is a product the NPPB gene found on human chromosome 1. The ventricles secrete BNP which results in decreased blood volume and pressure1. Together with ANP, and BNP contributes to the regulation of cardiovascular and renal homeostasis and blood pressure control by influencing the Renin-Angiotensin II-Aldosterone system (RAAS)1,2.
The prohormone form of BNP undergoes many cleavages to generate the biologically active BNP which results in fragments of various amino acid lengths including the NT-proBNP (1-76) fragment. Measuring the NT-proBNP (1-76) fragments of BNP provides a more accurate concentrations of the BNP in samples3,4,5 because it is more stable, has a longer half-live, and circulates at higher concentrations compared to the C-terminal biologically active BNP hormone6,7.
Research has shown that BNP is important to cardiovascular disease more recently to kidney disease and diabetes.
