We deliver scalable and robust GMP-compliant production processes for recombinant proteins.
Upstream process development for mammalian platforms
For small scale, high-throughput productions (microgram to milligram range of proteins), we typically apply our SCOUT® technology. This system integrates high-throughput cell culture using mini bioreactors (spin tubes; 2 – 20 mL working volume) with high throughput purification technology (spin-traps and spin-tubes) and matching analytical capabilities. Hereto, we have optimized CHO and HEK293 cell growth in our mini-bioreactors and have developed a number of media and medium feeds. To maximize the information generated during development, while limiting the number of experiments, a Design-of-Experiments (DOE) study format can be supported. For larger scale productions, we deploy a range of bioreactors up to 200 L depending on the development phase of the process. For suspension cultures, typically microwell plates, T-flasks, shake flasks or roller bottles in shake incubators, as well as WAVE Bioreactor™ systems and stirred single-use bioreactors are used, while for adherent cell cultures T-flasks, cell factories in static incubators or stirred tank reactors using microcarriers, iCELLis® systems or scale-X™ bioreactors in R&D and GMP. For these culture formats we can apply batch, fed-batch or perfusion culture protocols, depending project requirements.
All relevant in- and at line analytics are available to monitor and evaluate pivotal upstream process parameters to ensure optimal translation of the culture process to larger scales.
