Human AP12 ELISA Kit

Human Apelin 12 ELISA Kit is a competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the in vitro quantitative determination of human Apelin 12 in serum, plasma, tissue homogenates, and other biological fluids.

Apelin 12

Human Apelin 12 ELISA Kit (A79000) employs the competitive enzyme immunoassay technique for the quantitative measurement of human Apelin 12 in serum, plasma, tissue homogenates, and other biological fluids. The 96-well microtiter plate has been pre-coated with Apelin 12 antigen. During the incubation, Apelin 12 present in the samples or standards competes with the fixed amount of immobilized Apelin 12 for binding sites on the Biotinylated Anti-Apelin 12 Antibody. The more Apelin 12 present in a sample or standard, the less Biotinylated Anti-Apelin 12 Antibody that binds to the plate. Following incubation, unbound Biotinylated Anti-Apelin 12 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 Apelin 12 present in each sample or standard. The concentration of Apelin 12 can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
