Erratum

Murine monoclonal antibodies (mabs) are produced in either mouse ascites or bioreactors (spinner culture, stirred-tank reactor, airlift reactor, hollow-fiber reactor). Human mabs are produced solely in bioreactors. Encapsulation represents a special technology. Hybridoma cells have to be adapted prior to growth in bioreactors. Of crucial importance is the construction of over-producing cell lines by cell- and gene-technological methods. Manipulated cell lines often produce modified mabs.
