SpecificityThis assay has high sensitivity and excellent specificity for detection of Dehydroepiandrosterone (DHEA).
No significant cross-reactivity or interference between Dehydroepiandrosterone (DHEA) and analogues was observed.
SamplesSerum, plasma and other biological fluids
SensitivityThe minimum detectable dose of this kit is typically less than 14.2pg/mL.
PrecisionIntra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Dehydroepiandrosterone (DHEA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Dehydroepiandrosterone (DHEA) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%
Product Description specificalPrinciple of the Assay: The microtiter plate provided in this kit has been pre-coated with a monoclonal antigen. A competitive inhibition reaction is launched between biotin labeled Dehydroepiandrosterone (DHEA) and unlabeled Dehydroepiandrosterone (DHEA) (Standards or samples) with the pre-coated secondary antibody. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Dehydroepiandrosterone (DHEA) in the sample. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is reverse proportional to the Dehydroepiandrosterone (DHEA) level in the sample or standard.
