Principle of Assay
Human SLC10A2/ASBT ELISA Kit (A303176) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human SLC10A2/ASBT in serum, plasma, tissue homogenates, and other biological fluids. An antibody specific for SLC10A2/ASBT has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the SLC10A2/ASBT present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-SLC10A2/ASBT Antibody, which binds the captured SLC10A2/ASBT present in each well. Following incubation, unbound biotinylated detection 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 proportional to the amount of SLC10A2/ASBT captured in each well. The concentration of SLC10A2/ASBT can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
