Protein A chromatography

Affinity chromatography using Protein A ligand to selectively capture IgG antibodies from bioreactor harvests.

Where it's used

Downstream Purification & Bioseparation
Downstream purification converts crude bioreactor harvests into clinical-grade drug substance — chromatography (Protein A, IEX, HIC), tangential-flow filtration, and viral clearance together account for >50% of biomanufacturing CAPEX. The global DSP market exceeds $5B and grows at >8% CAGR driven by mAb and cell-gene therapy demand.
