原理：ELISA是以免疫学反应为基础，将抗原、抗体的特异性反应与酶对底物的高效催化作用相结合起来的一种敏感性很高的试验技术。由于抗原、抗体的反应在一种固相载体──聚苯乙烯微量滴定板的孔中进行，每加入一种试剂孵育后，可通过洗涤除去多余的游离反应物，从而保证试验结果的特异性与稳定性。在实际应用中，通过不同的设计，具体的方法步骤可有多种。即:用于检测抗体的间接法(图a)、用于检测抗原的双抗体夹心法(图b)以及用于检测小分子抗原或半抗原的抗原竞争法等等。比较常用的是ELISA双抗体夹心法及ELISA间接法。

Principle: ELISA is a highly sensitive immunological reaction test based technique, the antigen, the antibody specifically reacts with the enzyme substrate for efficient catalysis combined together. Since the antigen antibody reaction in a solid phase carrier ─ ─ polystyrene microtiter plate wells conducted after each addition of a reagent incubation, the excess can be removed by washing the free reactants to ensure the specificity of the test results and stability. In practice, the different design of specific process steps can have many. Namely: the indirect method for the detection of antibodies (Figure a), for the detection of antigen double antibody sandwich method (Figure b) and small molecules for the detection of antigen or hapten antigen competition law, and so on. More common is the double antibody sandwich ELISA and indirect ELISA.
