Product overview
Abcam’s proBNP Human ELISA Kit (ab193712) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human proBNP in serum, plasma and cell culture supernatants.
This assay employs an antibody specific for Human proBNP coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures proBNP present in the samples. The wells are washed and biotinylated anti-Human proBNP antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of proBNP bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Research areas

Function
Cardiac hormone which may function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3. -
Tissue specificity
Brain and also in atria, but at much lower levels than ANP. -
Sequence similarities
Belongs to the natriuretic peptide family. -
