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.
Virus Filtration
To ensure the safety of monoclonal antibody (mAb) therapeutics, downstream purification steps must effectively clear viruses of different physicochemical characteristics. Virus filtration is a dedicated viral clearance step used in most production processes that provides size-based virus removal and complements other virus removal technologies such as chromatography or viral inactivation through chemical treatment. Understanding the parameters that impact the virus filtration performance is essential to optimize virus filter capacity, flux, and retention.
