Description
Aviva Systems Biology FAM214A ELISA Kit (Human) (OKEH02422) is based on a competitive enzyme immuno assay technique. The microtiter well-plate in this kit has been pre-coated with an anti-Human FAM214A antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated FAM214A and incubated. The FAM214A found in the sample or standards competes with the biotinylated FAM214A for limited binding sites on the immobilized anti-Human FAM214A antibody. Excess unbound biotinylated FAM214A and sample or standard FAM214A 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 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 FAM214A captured in the well and inversely proportional to the amount of FAM214A which was contained in the sample or standard
