Principle of Assay
Rabbit Oxidized low-density lipoprotein ELISA Kit (A335438) employs the sandwich enzyme immunoassay technique for the quantitative measurement of rabbit Oxidized low-density lipoprotein in serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. An antibody specific for Oxidized low-density lipoprotein has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Oxidized low-density lipoprotein 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-Oxidized low-density lipoprotein Antibody, which binds the captured Oxidized low-density lipoprotein 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 Oxidized low-density lipoprotein captured in each well. The concentration of Oxidized low-density lipoprotein can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
