Principiul testului

Human IL-21R ELISA Kit (A7820) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human IL-21R in tissue homogenates or other biological fluids. An antibody specific for IL-21R has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the IL-21R present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-IL-21R Antibody, which binds the captured IL-21R present in each well. HRP-Avidin conjugate is then 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 proportional to the amount of IL-21R captured in each well. The concentration of IL-21R can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
