Transient Transfection

Your protein from mammalian in large scale within weeks

The recent rush in biopharmaceutical research and the advances in diagnostic assay development raised the need for significant amounts of correctly folded, fully processed and functional active recombinant tool proteins or preclinical material. While the use of stable transfected cell lines has a long-standing and successful history for the generation of biopharmaceutical proteins, these expression systems were generally regarded as being cumbersome, tedious and expensive. These drawbacks have been overcome by the recent development of large-scale transient transfection.

Production Systems

Our optimized transfection protocol can be applied to adherent as well as serum-free suspension cultures. While adherent cells are transfected in „Cell Factories”, suspension cells like HEK293 are grown in square bottles, spinners or fermenters. Operation scales vary from ml-tubes to final production volumes of 30 liters in our bioreactor systems.

With the experience of the production and purification of more than 1800 different monoclonal antibodies and the successful completion of nearly two hundred recombinant protein projects we are confident to solve your problem.

Obtain your mammalian cell derived protein in the same time as you would expect it for a bacterial expressed product.
