Monoclonal Antibodies in Immunodiagnosis and Immunotherapy provides targeted peer-reviewed research that advances the understanding of immune responses and the use of immunological methods for therapeutic purposes.Monoclonal antibodies are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope.Monoclonal antibodies (mAb or moAb) are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope (the part of an antigen that is recognized by the antibody

Given almost any substance, it is possible to produce monoclonal antibodies that specifically bind to that substance; they can then serve to detect or purify that substance. This has become an important tool in biochemistry, molecular biology, and medicine. When used as medications, non-proprietary drug names end in -mab (see "Nomenclature of monoclonal antibodies") and many immunotherapy specialists use the word mab anacronymically.
