ELISA

The Dehydroepiandrosterone Sulfate (DHEA-S) ELISA quantitates DHEA-Se in serum,plasma,urine,saliva,dried fecal extracts or cell culture medium.

Principle of the method

The Dehydroepiandrosterone sulfate (DHEA-S) Competitive ELISA research-use-only kit uses a specifically generated antibody to measure Dehydroepiandrosterone sulfate (DHEA-S) in serum,plasma,urine,and saliva samples,and in fecal extracts. The kit will also quantitatively measure DHEA-S present in tissue culture media samples. A DHEA-S standard is provided to generate a standard curve for the assay and all samples should be read off the standard curve. Standards or diluted samples are pipetted into a clear microtiter plate coated with an antibody to capture sheep antibodies. A DHEA-S-peroxidase conjugate is added to the standards and samples in the wells. The binding reaction is initiated by the addition of a polyclonal antibody to DHEA-S to each well. After a 2-hour incubation the plate is washed and substrate is added. The substrate reacts with the bound DHEA-S-peroxidase conjugate. After a short incubation,the reaction is stopped and the intensity of the generated color is detected in a microtiter plate reader capable of measuring at 450 nm.
