NPPB ELISA Kit (Rat)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Brain Natriuretic Peptide (BNP) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Brain Natriuretic Peptide (BNP) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Bnf; BNP; Brain natriuretic factor; brain natriuretic factor prohormone; brain natriuretic peptide; gamma-brain natriuretic peptide; iso-ANP; natriuretic peptide precursor B; natriuretic peptide precursor type B; natriuretic peptides B; preproBNP; proBNP.

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 (By similarity) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Brain Natriuretic Peptide (BNP) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Brain Natriuretic Peptide (BNP) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Brain Natriuretic Peptide (BNP), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Brain Natriuretic Peptide (BNP) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
