Description
Aviva Systems Biology GIP ELISA Kit (Rat) (OKEH02992) is based on a competitive enzyme immuno assay technique. The microtiter well-plate in this kit has been pre-coated with an anti-rat Gip antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated Gip and incubated. The Gip found in the sample or standards competes with the biotinylated Gip for limited binding sites on the immobilized anti-rat Gip antibody. Excess unbound biotinylated Gip and sample or standard Gip 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 Gip captured in the well and inversely proportional to the amount of Gip which was contained in the sample or standard
