Laboratory activity

Availability of tools for protein analysis has long been a major bottleneck in basic and translational science. In particular, highly specific (monoclonal) antibodies are the basis in many cell biology studies as well as in clinical diagnostics. To meet this continuous need, the Antibody Core Facility at DKFZ develops and produces high quality mouse and rat monoclonal antibodies targeting various kinds of antigens. More than 400 antibodies against 300 antigens have either been generated in the unit, or have been transferred to and are administered by the unit. Antibodies generated by the unit have been a prerequisite in a number of scientific discoveries and several are now used in routine diagnostics worldwide. Further, the unit supports licensing of proprietary monoclonal antibodies to companies.

The Antibody Core Facility uses state-of-the-art hybridoma technologies for production of monoclonal antibodies via the somatic fusion of lymphocytes from immunized mice or rats. We advise in the selection of antigens, immunize animals and perform screening of mother clones by e.g. ELISA, immunofluorescence or IHC. Clones having been tested successfully will be subcloned, expanded and maintained to guarantee long-time availability of materials. In addition, we provide non-GMP production and purification of antibodies. Lastly, we offer antibody sequencing, engineering and recombinant expression. These next generation engineered antibodies open new avenues of approach in biomedical research, diagnostics and as therapeutics.
