mAbs Downstream
Products for Development and Manufacturing
Higher cell densities and antibody titers from increasingly advanced upstream processes result in complex downstream purification challenges. The focus of downstream bioprocessing is efficient recovery and purification while controlling bioburden and assuring viral safety to provide drug safety for patients. The downstream workflow, which includes clarification, chromatography, concentration, viral clearance, and sterile filtration steps, is essential for ensuring monoclonal antibody (mAb) product quality, yield, safety, and sterility.
Affinity Chromatography
Protein A affinity chromatography is a robust, highly selective purification step that effectively captures monoclonal antibody (mAb) molecules separating them from impurities in complex clarified harvest material. This results in efficient mAb purity and recovery.
Consistent purification performance is required at all scales, from process development to production, and should be maintained through the long resin lifetime for optimized process economics.
For intensified or continuous processes, multi-column capture chromatography offers an effective approach to affinity separation which leverages the benefits of familiar protein A technology while reducing bottlenecks and increasing productivity.
