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

Features and Benefits

  • Increased dynamic binding capacity with smaller particle size and greater porosity than MabSelect medium.
  • MabSelect Xtra uses the same recombinant protein A ligand as MabSelect
  • Oriented coupling of recombinant Protein A to the matrix via an engineered C-terminal cysteine enhances IgG binding capacity.
  • Fewer regulatory concerns due to the total absence of mammalian culture in the ligand production and purification.
  • Prepacked HiTrap columns for process development, screening of purification conditions, and small-scale purification of Mabs.
