Cytiva, 17542404, MabSelect™ SuRe 70 protein A resin, 5 L

MabSelect™ SuRe 70 protein A resin with high dynamic binding capacity (DBC), enables highly cost-efficient capture of monoclonal antibodies (mAbs). The resin uses the well-established SuRe protein A ligand with good alkaline stability providing stable processing of mAbs.
Cost-efficient at low resin utilization, such as in clinical manufacturing.
Highest DBC of any of our MabSelect SuRe™ resins
Alkaline-stable, well-established protein A ligand, from the MabSelect SuRe resin, is stable when cleaned with 0.1 M NaOH for 200 cycles and approximately 100 cycles using 0.5 M NaOH.
Excellent for use in short bed heights and rapid resin cycling mode to further improve productivity in protein A step.
DBC at different residence times
The MabSelect™ SuRe 70 resin is based on a high-flow agarose base matrix with an average bead size of 50 μm. The optimized porosity enables a fast uptake of mAb, and the DBC is less dependent on residence time (RT) compared to other resins (e.g., MabSelect SuRe™ LX and MabSelect PrismA™ resins). The DBC for trastuzumab is higher than 70 g/L in a well-packed column at 6 min RT.
Alkaline-stable protein A ligand
As native protein A is sensitive to alkaline conditions, the ligand in MabSelect™ SuRe 70 resin, also used in the MabSelect SuRe™ resin, has been stabilized by engineering one of the IgG-binding domains of protein A. The MabSelect™ SuRe 70 resin is stable when cleaned with 0.1 M NaOH for 200 cycles and approximately 100 cycles using 0.5 M NaOH without performance loss.
Formats
MabSelect™ SuRe 70 resin is available as bulk resin in 25 mL, 200 mL, 1 L, 5 L, and 10 L containers. The resin can be ordered in pre-packed column formats such as HiTrap™ columns (1 and 5 mL), HiScreen™ columns, and on request as production scale ReadyToProcess™ columns. These formats enable use from lab-scale to commercial-scale manufacturing.
