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).

Magnosphere™ is a superparamagnetic particle for in vitro diagnostics and bio research applications.
Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.
A proven method for confirming protein purity and yield without the need for gel staining steps. Stain-free gels provide visual confirmation of protein purity and yield by gel electrophoresis in less than 30 minutes. Stain-free technology is perfect for drug discovery, drug development, and method development for preclinical research.
ReadyToProcess ULTA normal flow filter capsules are single-use filters designed for laboratory through process scale applications. Cytiva provides filtration solutions and support for integrated bioprocessing applications at every step and every scale of the drug development, validation and manufacturing process.
