实验流程
anti-TBEV IgG and IgG avidity is a solid-phase immunoanalytical test. The polystyrene strips are coated with specific antigen which bear immunodominant epitopes of TBEV. Anti-TBEV antibodies in samples bind to the immobilized antigens. The antibodies that do not bind are washed away and those that formed complexes with the antigens are later on recognised by animal anti-human IgG antibodies labelled with horseradish peroxidase. The presence of labelled antibodies is revealed by an enzymatic reaction with a chromogenic substrate. Negative samples do not react and the mild change in colour, if present, may be attributed to the reaction background. To determine avidity, each sample is applied in parallel to two wells, with the appropriate antibodies binding to the immobilized antigens. In the next step, one well is incubated with the wash solution, the other well with the urea solution. In the first well, specific antibodies with high and low avidity remain bound to the antigen. In the second well, low-avidity antibodies are released due to the concentrated urea solution, and only high-avidity antibodies remain complex with the antigen. The ratio between the optical density of the well with the urea solution and the well with the washing solution in percent expresses the relative avidity index (RAI).
