Human PPP1R12B ELISA Kit (A302679) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human PPP1R12B in serum, plasma, tissue homogenates, and other biological fluids. An antibody specific for PPP1R12B has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the PPP1R12B 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-PPP1R12B Antibody, which binds the captured PPP1R12B 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 PPP1R12B captured in each well. The concentration of PPP1R12B can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
