Learning Outcomes and Competencies First and foremost, the theoretical basics are taught in class for the planning as well as the realisation of antibody productions with CHO cells growing in suspension. Furthermore, students deal with the modelling of CHO cell growth and learn about important levers for increasing process efficiency in upstream processing. Upon completion of the module, students should be able to evaluate the correct strategy for process intensification and apply this in practice. In this context, they should also be able to describe factors influencing product quality.
 
The module also focuses on microcarrier technology for the cultivation of mammalian cells growing in suspension, but also those growing adherently, and on production processes based on insect cells and baculoviruses. Students should be aware of the differences from the mAb production processes covered previously and be able to apply developments that facilitate process scale-up such as the TIPS (titerless infected-cells preservation and scale-up) process or bead-to-bead transfer. This module is the basis for the cell culture technology 2 practicals.
Module Content The module consists of 3 blocks:
 
Block 1: mAb production with CHO cells growing in suspension
  • Brief repetition of necessary basics of cell culture as well as bioprocess technology
  • Complete mAb production (current and previous)
  • Modern USP of mammalian cell-based mAb productions and starting points to increase efficiency (T-shift, perfusion)
  • N-1 seed perfusion for superintensive inoculum production
  • High-seed fed-batch productions
  • Concentrated fed-batch
  • Continuous mAb productions
  • Special features of agitation and gassing in mAb productions
  • Harvesting and product separation in mAb productions
  • Cell growth modelling in mAb production processes
 
Block 2: Microcarrier technology and its challenges in the cultivation of mammalian cells growing both in suspension and adherently.
  • Historical excursus and main applications
  • Microcarrier types, their selection and suitable bioreactors
  • Development of microcarrier-based processes
  • Processes with bead-to-bead transfer
 
Block 3: Production processes with insect cells and baculoviruses
  • History
  • Cell lines
  • Special features of insect cell cultivation compared to mammalian cells
  • Insect cell metabolism and culture media
  • Two-phase vs. single-phase processes (TIPS procedures)
  • Virus-like particle – vaccine production
