Anti-isotype Antibody Production

Date: 2018-08-27 Author: Leading Biology Click: 785


The immune process of animals is done by the participation of a variety of organs and cells, so, even for the same antigen immunization, there is a great difference between the antibody produced by the same antigen in the same immune cycle. Taking people and mice as an example, there are five subtypes of antibodies in the body, they are: IgG, IgA, IgM, IgE and IgD, of which IgG is divided into four subtypes according to the location of the disulfide bond, which also called homotypes. In some immunological tests, in order to observe the stage of the immune response of the tested animal, it is often needed to use the subtype of the main antibody produced by the animal as a clue. Capture or mark a specific subtype of antibody,  at the same time have no specific identification of antibodies against specific antigens, this is the so-called anti specific subtype antibody, it is the basic material for the identification of antibody subtypes.
