MabSelect Xtra™ and MabSelect™ have the same recombinant protein A ligand.
- High dynamic binding capacity (up to 30% higher than MabSelect™) and suitable for for high expression feedstocks
- Improved process economics through reduced raw materials costs and/or reduced number of cycles
- High capacity for large Fc-fusion proteins
- Very low, unspecific binding due to high ligand selectivity and matrix hydrophilicity
- Slightly lower pressure/flow properties compared to MabSelect™
MabSelect™ Xtra is based on a high-flow agarose base matrix with increased porosity and a decreased particle size, which results in higher binding capacity. In addition, MabSelect™ Xtra has a higher capacitiy for large Fc-fusion proteins.
