Upstream Processing Steps
Bioprocessing steps, from the cryogenic vials to the main culture:
- Thawing of the cryogenic vial.
- Shake flask cultures, from 0.5L to 1L.
- Seed cultures, from 10L to 200L.
- Main culture, 1000L.
Cell culture media serve as an environment where the cells can expand, and it provides nutrients for the cells to grow and express the biomolecules of interest.
Cell culture and fermentation media must contain precise quantities of nutrients and be sterile, and CPPs—such as pH, dissolved oxygen (DO), and culture yield weight—are carefully monitored in situ and real-time to enable reproducible and reliable results during the bioprocess and downstream processing.
