Acidic and basic species analyzed using ion-exchange chromatography (IEX) or iso-electric focusing (cIEF).

The was defined such that any combination within ranges (e.g., Protein A elution pH 3.6–4.0, polishing flow rate 150–250 cm/h) yielded CQA compliance. A Mab A Case Study In Bioprocess Development

The dihydrofolate reductase (DHFR) selection system was utilized, employing methotrexate (MTX) to drive gene amplification. Two orthogonal polishing steps were deployed to clear

Two orthogonal polishing steps were deployed to clear remaining aggregates, fragments, HCP, and leached Protein A. The goal of is to isolate a single,

The journey starts by engineering the factory. A gene encoding the desired antibody is transfected into a stable host cell line, most commonly CHO cells, which are favored for their ability to perform human-like post-translational modifications and grow robustly in suspension culture. The goal of is to isolate a single, high-producing, and stable clone that can consistently deliver the required quantity and quality of the mAb.

The cell culture fluid must be clarified efficiently to protect downstream chromatography columns. A two-stage depth filtration train was implemented.
