A general representation of the method used to produce monoclonal antibodies [1] [2] A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.
By providing information on mechanism of action, epitope mapping is a critical component in therapeutic monoclonal antibody (mAb) development. Epitope mapping can reveal how a mAb exerts its functional effects - for instance, by blocking the binding of a ligand or by trapping a protein in a non-functional state.
Since the antibodies in a well are produced by the same B cell, they will be directed towards the same epitope, and are thus monoclonal antibodies. The next stage is a rapid primary screening process, which identifies and selects only those hybridomas that produce antibodies of appropriate specificity.

The nomenclature of monoclonal antibodies is a naming scheme for assigning generic, or nonproprietary, names to monoclonal antibodies.An antibody is a protein that is produced in B cells and used by the immune system of humans and other vertebrate animals to identify a specific foreign object like a bacterium or a virus.
The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. Types of monoclonal antibodies with other structures than naturally occurring antibodies. The abbreviations in the column Type are as follows: mab: whole monoclonal antibody; Fab: fragment, antigen-binding (one arm)
Methods for functionally mapping epitopes often use binding assays such as western blot, dot blot, and/or ELISA to determine antibody binding. [20] Competition methods look to determine if two monoclonal antibodies (mABs) can bind to an antigen at the same time or compete with each other to bind at the same site. [20]
Today, chromatographic separation using protein A immobilized on porous substrates is the most widely established method for purifying monoclonal antibodies (mAbs) from harvest cell culture supernatant. [21] The choice of protein A as the preferred method is due to the high purity and yield which are easily and reliably achieved.
