Principle of Assay
Human COQ10B ELISA Kit (A75988) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human COQ10B in serum, plasma, tissue homogenates, and other biological fluids. An antibody specific for COQ10B has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells, and the COQ10B present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with an HRP-labeled Anti-COQ10B Antibody, which binds the captured COQ10B present in each well. Following incubation, unbound detection antibody is removed by washing. TMB substrate solution is then added to visualize the HRP enzymatic reaction, producing a blue-coloured product that changes to yellow after the addition of acidic stop solution. The intensity of the yellow colour is proportional to the amount of COQ10B captured in each well. The concentration of COQ10B can then be calculated by measuring the O.D. absorbance at 450 nm using a microplate reader and referring to the standard curve.
