Brain Natriuretic Peptide (BNP) ELISA Kit


Human BNP ELISA kit is designed for analysing in vitro quantitative levels of brain natriuretic peptide (natriuretic peptide B, BNP, ventricular natriuretic peptide, B-type natriuretic peptide) in human serum, plasma, other biological fluids, cell culture supernatant and cell lysates. This assay has a minimum sensitivity limit of 9.38 pg/ml.


Brain natriuretic peptide (BNP) which can also be called B-type natriuretic peptide or natriuretic peptide B or ventricular natriuretic peptide, it is secreted in response to excessive stretching of the heart muscle cells by the ventricles. BNP is secreted attached to a prohormone (NT-proBNP), this is a 76 amino acid N-terminal fragment and it is biologically inactive.

Once it is released brain natriuretic peptide will bind and activate the atrial natriuretic factor receptors (NPRA) and the physiological actions include decreasing central venous pressure and systemic vascular resistance, in addition to an increase in natriuresis. The overall action of both BNP leads to a decrease in cardiac output, which ultimately results in a reduction in blood volume that follows diuresis and natriuresis. Both BNP and NT-proBNP have been useful in screening and prognosis of heart failure. The levels of both of these is typically elevated in patients having left ventricular dysfunction. Also, recombinant BNP and nesiritide have been vital in treating decompensate heart failure.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
