Monoclonal antibodies produced against antigenic determinants present in complex mixtures of proteins.

This overview provides information concerning the production of monoclonal antibodies (MAbs) against specific antigenic determinants present in complex mixtures of proteins. We review five specific techniques for the production of these antibodies (Abs): (a) So-called "shotgun," non-selective approach; (b) cascade procedure; (c) lymphocyte "panning"; (d) cyclophosphamide elimination of unwanted Ab producers; and finally (e) use of polyclonal antisera to extinguish unwanted antibody production. We discuss the relative advantages and disadvantages of these various procedures, and suggest alternative strategies by which specific MAbs might be generated.
