Braunschweig / Toronto: antibodies without animal testing Featured

In future it will be possible to produce economically antibodies, holding a key role in the investigation of biological and medical questions, without the use of animals in large numbers.

An international group of scientists, with substantial involvement of the Technical University of Braunschweig, Department of Professor Stefan Dübel, and the Structural Genomics Consortium, University of Toronto under the supervision of Dr. Aled Edwards, could this first in a systematic study of its kind to demonstrate alternative production methods. The study results are published in the journal Nature Methods.

So far the production of antibodies, key reagents for cell biological and biomedical research which can also be used as pharmaceuticals, was largely dependent on animals. In particular, the antibody phage display technology for which Prof. Dübel was co-inventor was very helpful here. Instead using animals to produce new antibodies in all steps the researchers apply bacteria in vitro. In the context of the international consortium of Canadian, U.S., Sweden, Australia and England the new antibodies were tested and the methods were validated in detail by systematic analysis of an application on a large scale.
