Part of the MabSelect protein A resin family

MabSelect SuRe LX is a member of the MabSelect family of protein A resins for the capture of monoclonal antibodies at process scale. MabSelect SuRe LX shares features and benefits of MabSelect and MabSelect SuRe such as a rigid, high-flow agarose matrix that ensures excellent pressure/flow properties, low non-specific binding that leads to low impurity levels in the eluate pool, and an oriented ligand coupling for excellent binding capacity. It also features the same alkali-tolerant rProtein A ligand as MabSelect SuRe. This protein ligand provides greater stability than conventional protein A-based resins in the alkaline conditions used in cleaning-in-place (CIP) and sanitization protocols.

Enhanced stability of the protein ligand

The enhanced alkali stability of MabSelect SuRe LX improves process economy and product quality; cleaning can be performed with cost-effective reagents such as sodium hydroxide, eliminating the need for expensive and hazardous cleaning agents such as Gua-HCl. Process economy is also improved by the increased dynamic binding capacity of MabSelect SuRe LX.

Just as for MabSelect SuRe, the novel ligand construct of MabSelect SuRe LX has been proven to have an increased stability towards proteases. Therefore, the level of leakage of the MabSelect SuRe LX ligand during elution is low.

Purification platform design advantage

MabSelect SuRe has been demonstrated to give generic elution conditions for different monoclonal antibodies, which can be applied also to MabSelect SuRe LX as it utilizes the same ligand. This is an advantage when designing generic purification platform processes. The feature is also correlated to the construction of the MabSelect SuRe protein ligand.
