Monoclonal antibodies (mAb or moAb) are monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell, in contrast to polyclonal antibodies which are made from several different immune cells.onoclonal antibodies are typically made by fusing myeloma cells with the spleen cells from a mouse that has been immunized with the desired antigen. However, recent advances have allowed the use of rabbit B-cells to form a rabbit hybridoma.
Monoclonal antibodies have monovalent affinity, in that they bind to the same epitope. 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.hen used as medications, the non-proprietary drug name ends in-mab (see  Nomenclature of monoclonal antibodies ), and many immunotherapy specialists use the word mab anacronymically.
