CYP21A2 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

21-OHase; CA21H; CAH1; CPS1; CYP21; CYP21B; Cytochrome P450 21; cytochrome P450 XXI; cytochrome P450, family 21, subfamily A, polypeptide 2; cytochrome P450, subfamily XXIA (steroid 21-hydroxylase, congenital adrenal hyperplasia), polypeptide 2; Cytochrome P-450c21; Cytochrome P450-C21; cytochrome P450-C21B; P450c21B; steroid 21 hydroxylase; steroid 21-hydroxylase; steroid 21-monooxygenase.

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 Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2) . 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 Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2), 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 Cytochrome P450 Family 21 Subfamily A Member 2 (CYP21A2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
