Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Stability

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

ELISA Kit for 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1)

Test principle

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 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1). 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 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1), 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 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
