![Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media]( "Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media")
Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography MediaMonoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).

Removal Of Host Cell Proteins During Monoclonal Antibody Purification
Protein A chromatography is a widely used and highly successful method of purifying recombinant monoclonal antibodies. However, since Protein A has high affinity for antibodies, harsh conditions such as low pH are often required to elute monoclonal antibodies from Protein A affinity columns. By 3M Purification Inc
