2,Applications & Principles

     Technical Theory:

Enzyme-labeled Chemiluminescence Immunoassay Technology

     Test Procedure:

1) Sandwich ELISA:Solid Phase Chemiluminescence Enzyme Immunoassay, taking micro plate as its carries, follows the sandwich methodology. The methodology uses 2 specific antibodies which recognize discrete sites on the unknown molecule. The first antibody is precoated onto the wells of the micro plate. It captures antigen in the blood serum after being added into the sample. The other antibody, connected with HRP, is allowed to bind to the antigen. Thus, the immune compounds of antibody -antigen- labeled antibody come into being on the surface of the micro plate. After unbound antigen and HRP-antigen-antibody are removed with a wash by solution, chromogenic substrate solution is added to determine the relative luminescence intensity. According to the relative luminescence intensity of the known antigen concentration of the calibration materials, standard curve is drawn and regression line is available via dual-logarithm mathematical model. Then, the concentration of antigen present in the unknown sample can be calculated.

2)Competitive ELISA: Solid Phase Chemiluminescence Enzyme Immunoassay, taking micro plate as its carries, follows the competitive methodology. Antigen is coated in advance onto the wells of the micro plate. After the test sample is added, free antigen from the test sample and the HRP-labeled antigen compete for the immobilized antibody-binding sites on the wells. Thus, the immune compounds consisting of antibody-antigen and antibody-HRP- labeled antigen come into being on the surface of the micro plate. After unbound antigen and HRP-antigen are washed off by solution, pre-set chromogenic substrate solution is added to determine the relative luminescence intensity. The more the free antigen in the sample, the less the amount of conjugated HRP-antigen. According to the known concentration of the calibration materials and its related luminescence intensity, dosage-reaction curve is drawn and regression line is available after the fitting process. Then, the concentration of antigen present in the unknown sample can be calculated.
