Our Microbial Cell Line Development group has extensive experience in establishing, optimizing, and characterizing high cell density E. coli and Pichia fed-batch processes.
For E. coli, suitable expression vectors and host strains are available, and the microbial cGMP cell banking services are embedded in the development group. The overall focus is to develop high-yielding cell lines and processes that are robust and scalable, with high productivity in regulatory-friendly media.
