![Monoclonal Antibody Purification Platform Using High-Capacity Protein A And Mixed-Mode Chromatography]( "Monoclonal Antibody Purification Platform Using High-Capacity Protein A And Mixed-Mode Chromatography")
Monoclonal Antibody Purification Platform Using High-Capacity Protein A And Mixed-Mode ChromatographyThe first step in purification of an important class of therapeutic proteins, the polyclonal or monoclonal antibodies (mAbs), is their capture from plasma or tissue culture supernatants. Protein A–based media are by far the most common class of affinity products used for this purpose.

![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).
