The human body is protected by "immunity", its own defense system against foreign substances. Excerpted from the system is what is called "antigen-antibody reaction", which has been made easy to understand in a game format for this exhibit. If you can successfully transform your protectors antibodies to react to the five different shapes of blocks antigens that drop from above, and bring them into contact with the bottoms of the blocks, you can eliminate the blocks. Transform your protectors skillfully so that you can react to foreign substances that come in a variety of shapes to achieve high scores. Antigen-Antibody Reaction and VaccinesNumerous substances and cells are involved in the immune system of the human body.
The antigens and the antibodies combine specifically with each other. This interaction between them is called Antigen-Antibody reaction. It may be abbreviated.

Now that you know what an antigen and antibody are, let us consider the interaction between them. The strength of interaction between antibody and antigen at single antigenic sites can be described by the affinity of the antibody for the antigen. The greater the interaction, the stronger the affinity. Avidity is perhaps a more informative measure of the overall stability or strength of the antibody-antigen complex. It is controlled by three major factors: antibody epitope affinity, the valence of both the antigen and antibody, and the structural arrangement of the interacting parts.

Gene Mayer, Ph. The combining site of an antibody is located in the Fab portion of the molecule and is constructed from the hypervariable regions of the heavy and light chains. X-Ray crystallography studies of antigen-antibody interactions show that the antigenic determinant nestles in a cleft formed by the combining site of the antibody as illustrated in Figure 1.
Last reviewed: April A reaction that occurs when an antigen combines with a corresponding antibody to produce an immune complex.
