Antigen antibody interaction

antigen antibody interaction Antigen-antibody reaction antigen-antibody reaction article by: baumgarten, alexander department of laboratory medicine, school of medicine, yale university, new haven,  a reaction that occurs when an antigen combines with a corresponding antibody to produce an immune complex.

Antigen-antibody interaction antigen–antibody interactions are generally a result of a combination of ionic, hydrophobic, and hydrogen bonds formed between amino acids in the specific antigenic determinant of the antigen (epitope) and the protein loops of the complementarity determining regions (cdrs), which are located in the variable regions of the heavy and light chain of the antibody molecule.

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 thus, our concept of antigen-antibody reactions is one of a key ( ie the antigen) which fits into a lock ( ie the antibody.

•a strong antigen – antibody interaction depends on avery close fit between the antigen and antibody whichrequires high degree of specificityproperties of antigen – antibody reaction:the properties of antigen and antibody can beexplained with the help of three points they are:• antibody affinity• antibody avidity• cross reaction 13.

Antigen-antibody interaction, or antigen-antibody reaction, is a specific chemical interaction between antibodies produced by b cells of the white blood cells and antigens during immune reaction 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. A strong antigen-antibody interaction depends on a very close fit between antigen and antibody the combined strength of the non-covalent interactions between a single antigen-binding site on an antibody and a single epitope is the affinity of the antibody for that epitope.

Antigen antibody interaction

Antigen-antibody interaction is a particular chemical interaction between antibodies formed by b cells of the white blood cells and antigens during immune reaction it is the fundamental reaction in the body by which the body is protected from complex extraneous molecules, such as pathogens and their chemical toxins. Interactions between antigen and antibody involve non-covalent binding of an antigenic determinant (epitope) to the variable region (complementarity determining region, cdr) of both the heavy and light immunoglobulin chains these interactions are analogous to those observed in enzyme-substrate interactions and they can be defined similarly.

Antigen-antibody interactions involve a variety of forces the interaction between an antibody and its antigen can be disrupted by high salt concentrations, extremes of ph, detergents, and sometimes by competition with high concentrations of the pure epitope itself.

Interactions between antigen and antibody involve non-covalent binding of an antigenic determinant (epitope) to the variable region (complementarity determining region, cdr) of both the heavy and light immunoglobulin chains.
