Principiul testului

Human Interferon alpha 21 ELISA Kit (A87113) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human Interferon alpha 21 in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for Interferon alpha 21. Standards and samples are added to the wells, where Interferon alpha 21 binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for Interferon alpha 21 is added to the wells. The detection antibody binds the captured Interferon alpha 21 to form an antibody-antigen-antibody sandwich complex. After further incubation and washing, HRP-Streptavidin conjugate is added to the wells. TMB substrate solution is then added to visualize the HRP enzymatic reaction. This produces a blue-coloured product that changes to yellow following addition of acidic stop solution. The intensity of the yellow colour is directly proportional to the amount of Interferon alpha 21 captured in each well. The concentration of Interferon alpha 21 is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
