Description

General description

Determined at 10% breakthrough by frontal analysis at a mobile phase velocity of 500 cm/h in a column with a bed height of 20 cm.

MabSelect^™ Xtra, with extra high dynamic binding capacity, is a member of the MabSelect^™ family. Developed to meet the demands of increasing levels of expression in monoclonal antibody feedstocks.

MabSelect^™ Xtra has the same recombinant Protein A ligand as MabSelect^™ but is based on a high-flow agarose base matrix with increased porosity and a slightly decreased particle size compared to MabSelect. This results in higher capacity—MabSelect^™ Xtra has about 30% higher dynamic binding capacity for IgG than currently available Protein A chromatography media.

In addition, MabSelect^™ Xtra has a higher capacitiy for many Fc-fusion proteins.

The medium provides a lower overall production cost due to the possibility of processing concentrated feedstocks in fewer batches.

MabSelect^™ Xtra is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development.
As member of the BioProcess media range, MabSelect^™ Xtra meets industrial demands with security of supply and comprehensive technical and regulatory support.

pH below 3 is sometimes required to elute strongly bound IgG species. However, protein ligands may hydrolyze at very low pH.

Features and Benefits

• Higher dynamic binding capacity than currently available Protein A chromatography media.
• Improved process economics through reduced raw materials costs and/or reduced number of cycles
• High purity capture due to high ligand selectivity and matrix hydrophilicity
• Slightly lower pressure/flow properties compared to MabSelect^™ SuRe^™ and MabSelect
