Human NT-proBNP(N-Terminal Pro-Brain Natriuretic Peptide) Introduciton

The N-terminal prohormone of brain natriuretic peptide (NT-proBNP or BNPT) is a prohormone with a 76 amino acid N-terminal inactive protein that is cleaved from the molecule to release brain natriuretic peptide. Both BNP and NT-proBNP levels in the blood are used for screening, diagnosis of acute congestive heart failure (CHF) and may be useful to establish prognosis in heart failure, as both markers are typically higher in patients with worse outcome. The plasma concentrations of both BNP and NT-proBNP are also typically increased in patients with asymptomatic or symptomatic left ventricular dysfunction and is associated with coronary artery disease and myocardial ischemia.

Human NT-proBNP(N-Terminal Pro-Brain Natriuretic Peptide) ELISA Kit Test method

This kit uses sandwich ELISA to detect the concentration of Human NT-ProBNP.

Human NT-ProBNP-specific monoclonal antibody has been pre-coated in the wells of the supplied microplate. Standards samples and controls are added to interact with the immobilized antibody. A sandwich complex is formed by additional anti-Human NT-ProBNP antibody with HRP-Streptavidin. TMB solution is added to react with the sandwich for ming optical signal measured by microplate reader. The concentration of Human NT-ProBNP in the sample can be calculated by comparing the absorbance of the sample with the standard curve.
