CORIN ELISA Kit (Mouse)

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

Atrial natriuretic peptide-converting enzyme; AV273130; Corin; L; low density lipoprotein receptor-related protein 4; low density lipoprotein-related protein 4; Lrp4; pro-ANP-converting enzyme.

Serine-type endopeptidase involved in atrial natriuretic peptide hormone (NPPA) processing. Converts through proteolytic cleavage the non-functional propeptide NPPA into the active hormone, thereby regulating blood pressure in heart and promoting natriuresis, diuresis and vasodilation. Proteolytic cleavage of pro-NPPA also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Also acts as a regulator of sodium reabsorption in kidney. May also process pro-NPPB the B-type natriuretic peptide.

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