Explain The Antigen Antibody Reaction Diagram. All antibodies have at least two antigen binding sites represented as their Fab 2. The antigens and antibodies combine by a process called agglutination. However an antigen may not be able to induce the formation of an antibody and therefore may not be an immunogen. The antibody that cause agglutination are called agglutinins and particulate antigens aggregated are called agglutinogens.

Such assays called particle agglutination PA are based on the ability of sera containing HIV antibodies to crosslink small particles containing HIV antigens on the surface. Antigens contain different antigenic determinants epitopeses that can elicit different types of antibodies In. Antigens could be anything like a pathogen or bacteria or fungi or even virus. The interaction between antigen and antibody occurs in two stages. Antibodies recognize molecular shapes epitopes on antigens. Centrifugation is the most widely used way to enhance antigenantibody reactions.
It is the fundamental reaction in the body by which the body is protected from complex foreign molecules such as pathogens and their chemical toxins.
They cause diseases or allergic reactions. Avidity is the strength of multiple interactions between antigen and antibody with multiple binding sites. Types of Antigen Antibody ReactionThe types of antigen antibody reactions are Precipitation Reaction Agglutination Reaction Complement Fixation ELISA Enzyme Linked ImmunoSorbent Assay Immunofluorescence. The mechanism of antigen-antibody reactions has been an attractive subject for experimentation and speculation ever since the early days of immunology. Centrifugation is the most widely used way to enhance antigenantibody reactions. 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.
