Human NT-proBNP ELISA kit can be used for measuring in vitro quantitative levels of N-terminal pro-brain natriuretic peptide, NT proBNP, NT-proBNP, BNPT) in human cell culture supernatant, plasma, cell lysates, serum and many other biological fluids. This assay has a minimum sensitivity limit of 2.0 pg/ml.
N-terminal prohormone of brain natriuretic peptide (also called NT-proBNP, BNPT and NT proBNP) is an inactive protein which is released as a result of cleaving the N-terminal 76 amino acid fragment from brain natriuretic peptide. Both the bioactive BNP and the inactive NT proBNP have been useful in the diagnosis and management of heart failure. Their concentrations in blood are vital for the diagnosis and screening of acute congestive heart failure and can help to establish the prognosis in heart failure, since both of these marker are often elevated in patients with the worse outcome. Some of the main advantages NT-proBNP have over BNP is that it possesses superior stability, higher circulating levels and a relatively smaller amount of serum is needed to carry out a measurement.
