Specialists for plasmid DNA production.

Pioneers in plasmid DNA production

Gene vaccinations and gene therapies have set new standards. Plasmid DNA (pDNA) has turned into a key factor for successful research, development and commercialization of potentially game changing products.

We, at Boehringer Ingelheim, are pioneers in the manufacturing of pDNA. We have developed and continuously improved a best in class production process for highest-quality pDNA to leverage the potential of new therapeutic or prophylactic applications for our customers. As one of the world's leading contract manufacturers, Boehringer Ingelheim BioXcellence™ can provide pDNA from research to GMP grade in lot sizes ranging from multi-grams to kilograms.

Our platform technologies in E. coli host strain development, fermentation, and downstream processing, as well as a versatile analytical concept enable fast time to clinic and time to market. Our sound technical expertise combined with high quality and regulatory competence has satisfied more than 14 different customers around the world with pDNA of various sizes.
