Nppa ELISA Kit (Mouse)

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

Hormone playing a key role in cardiovascular homeostasis through regulation of natriuresis, diuresis, and vasodilation. Also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.

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 Atrial Natriuretic Peptide (ANP) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Atrial Natriuretic Peptide (ANP) . 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 Atrial Natriuretic Peptide (ANP), 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 Atrial Natriuretic Peptide (ANP) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
