Description

MabSelect SuRe LX is a member of the MabSelect family of affinity chromatography media for the capture of monoclonal antibodies (MAbs) 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 optimal binding capacity. It also features the same alkali-tolerant rProtein A ligand as MabSelect SuRe. This ligand provides greater stability than conventional protein A-based media in the alkaline conditions used in cleaning-in-place (CIP) and sanitization protocols. The enhanced alkali stability of MabSelect SuRe 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.
