High productivity expression technologies
The broad spectrum of microbial and yeast hosts at Boehringer Ingelheim allows the selection of the most suitable production system in terms of economy, product quality and efficiency.
High-performance expression of peptides and proteins
E.coli: For high-performance expression of peptides and proteins in inclusion bodies, titers up to 20 g/L are achieved. This is four-fold higher than the current industrial standard.
Pichia pastoris: For the methylotroph pichia pastoris explosion-proof fermentation plants are in place. The productivity for Fab fragments is in the range of 2 g/L.
Hansenula polymorpha yeast strains: Boehringer Ingelheim RCV GmbH & Co KG has access to high-titer hansenula polymorpha yeast strains with titers above 5 g/L.
Saccharomyces cerevisiae fermentation technology is established with a productivity of more than 3 g/L.
