Description
Aviva Systems Biology Tmpo ELISA Kit (Mouse) (OKEH06592) is based on a competitive enzyme immunoassay technique. The microtiter well-plate in this kit has been pre-coated with an anti-Tmpo antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated Tmpo and incubated. The Tmpo found in the sample or standards competes with the biotinylated Tmpo for limited binding sites on the immobilized anti-Tmpo antibody. Excess unbound biotinylated Tmpo and sample or standard Tmpo is washed from the plate. Avidin-HRP conjugate is added, incubated and washed. An enzymatic reaction is then produced through the addition of TMB substrate which is catalyzed by the immobilized HRP to generate a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration is measured by reading the absorbance at 450 nm which is quantitatively proportional to the amount of biotinylated Tmpo captured in the well and inversely proportional to the amount of Tmpo which was contained in the sample or standard
