Because an antibody fits precisely with an antigen an antibody that binds to one antigen cannot bind to another antigen. Antigen Antibody Reaction Agglutination is defined as the formation of clumps of cells or inert particles by specific antibodies to surface antigenic components direct agglutination or to antigenic components adsorbed or chemically coupled to red cells or inert particles passive hemagglutination and passive agglutination respectively.

Antigen-antibody complexes form only after the nuclear contents of a cell are released into the bloodstream during the normal course of cell death or as a result of inflammation. Avidity is the strength of multiple interactions between antigen and antibody with multiple binding sites. Antigen-antibody reactionthe reversible binding of antigen to homologous antibody by the formation of weak bonds between antigenic determinants on antigen molecules and antigen binding sites on immunoglobulin molecules. 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. It is a Y shaped molecule which is basically a protein that is produced by the B cells of the immune system. An antibody has a paratope that can recognize the epitope that is present on the surface of the antigen.
Antibody can inactivate the invading agent in.
The preferred sensor for detecting selected antigen-antibody reactions comprises a tube shaped reaction chamber for mixing a preselected amount of a pH adjusted aqueous solution to be tested with an antibody a heater for increasing a speed of an antigen-antibody reaction of the pH adjusted aqueous solution and the antibody a first sensor affixed to the. 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. PA has advantages of sensitivity and relatively high inherent specificity because. Antigen-antibody complexes form only after the nuclear contents of a cell are released into the bloodstream during the normal course of cell death or as a result of inflammation. Aggregation of cells due to antibody binding is known as Agglutination. For instance lipids and all low-molecular-weight.

Thus our concept of antigen-antibody reactions is one of a key ie. Invading microorganisms have antigens. The antigen-antibody reactions that are used most in blood banking are known as hemagglutination ie they cause the agglutination of red cells. ELISA also known as an enzyme linked immunosorbent assay is a biochemical. The noncovalent interactions that form the basis of antigen -antibody Ag-Ab binding include hydrogen bonds ionicbonds hydrophobic interactions and van der Waals interactions.

The antigen-antibody reaction is widely used in laboratory diagnostics including immunohaematology. Laboratory tests to detect antibodies and antigens outside of the body eg in a test tube are called in vitro assays. All immunogens are also antigens because they react with corresponding antibodies see illustration. However an antigen may not be able to induce the formation of an antibody and therefore may not be an immunogen. But we know that some antibodies IgM and IgA exist in secreted form as a multi-antibody complex.

But we know that some antibodies IgM and IgA exist in secreted form as a multi-antibody complex. It is the fundamental reaction in the body by which the body is protected from complex foreign. 8 are highly specific and both fit into each other like a lock and key. When this involves red blood cells it is called haemolysis and causes the release of haemoglobin. The antigens and antibodies combine by a process called agglutination.

When both antibodies and their corresponding antigens are present in a solution we can often observe a precipitation reaction in which large complexes lattices form and settle out of solution. Thus the relationship between antigen concentrations as indi-cated by the antigenantibody complex formation and light scattering approaches linearity.
