Human Dehydroepiandrosterone Sulfate ELISA Kit is a competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the in vitro quantitative determination of human Dehydroepiandrosterone Sulfate in serum, plasma, tissue homogenates, and other biological fluids.

Applications:Competitive ELISA, Host:, Reactivity:Human, Product range:15.625-1000 ng/ml, Sensitivity:9.375 ng/ml, Storage:Store at +4?C. Do not use past expiration date!, Target:Dehydroepiandrosterone Sulfate, Sample type:Serum, plasma, tissue homogenates, and other biological fluids, Principle assay:Human Dehydroepiandrosterone Sulfate ELISA Kit (A74764) employs the competitive enzyme immunoassay technique for the quantitative measurement of human Dehydroepiandrosterone Sulfate in serum, plasma, tissue homogenates, and other biological fluids. The 96-well microtiter plate has been pre-coated with Dehydroepiandrosterone Sulfate antigen. During the incubation, Dehydroepiandrosterone Sulfate present in the samples or standards competes with the fixed amount of immobilized Dehydroepiandrosterone Sulfate for binding sites on the Biotinylated Anti-Dehydroepiandrosterone Sulfate Antibody. The more Dehydroepiandrosterone Sulfate present in a sample or standard, the less Biotinylated Anti-Dehydroepiandrosterone Sulfate Antibody that binds to the plate. Following incubation, unbound Biotinylated Anti-Dehydroepiandrosterone Sulfate Antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is inversely proportional to the amount of Dehydroepiandrosterone Sulfate present in each sample or standard. The concentration of Dehydroepiandrosterone Sulfate can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve, Assay type:Competitive (quantitative), Detection type:Colorimetric, Platform:Pre-coated Microplate (12 x 8 well strips), Assay time:4h 30m
