Description
Aviva Systems Biology CYP4F2 ELISA Kit (Human) (OKEH01660) is based on a competitive enzyme immuno assay technique. The microtiter well-plate in this kit has been pre-coated with an anti-human CYP4F2 antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated CYP4F2 and incubated. The CYP4F2 found in the sample or standards competes with the biotinylated CYP4F2 for limited binding sites on the immobilized anti-human CYP4F2 antibody. Excess unbound biotinylated CYP4F2 and sample or standard CYP4F2 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 CYP4F2 captured in the well and inversely proportional to the amount of CYP4F2 which was contained in the sample or standard
