Process Development

---

Upstream processing involves the early stages of bioprocess development, beginning with cell line selection, seed train preparation, and controlled cultivation. The goal is to optimize cell growth and maximize expression of the desired biomolecule. This includes establishing ideal culture conditions, such as media composition, nutrient balance, feeding strategies, and bioreactor parameters. Through systematic optimization, upstream development ensures robust, scalable, and reproducible production performance that supports downstream purification and overall process reliability. 

Downstream processing focuses on the extraction, purification, and refinement of the target biomolecule after cultivation. Once the product is released into the supernatant or retained within the cells, it undergoes a series of steps designed to remove impurities while preserving biological activity. Typical downstream operations include cell separation, filtration, chromatography, concentration, and polishing. Each step is optimized to enhance product purity, yield, and stability. By fine‑tuning these purification strategies, downstream development ensures that the final product meets stringent quality, safety, and regulatory requirements.
