The recombinant protein A ligand of Cyitva's MabSelect SuRe ™ has been engineered to withstand 0.1–0.5 M NaOH, enabling efficient cleaning of the chromatography resin.
- In process-scale applications, this NaOH tolerance extends the lifetime of the resin and allows for the use of rigorous and cost-effective CIP and sanitization protocols.
- In research applications, this NaOH tolerance enables the purification of multiple antibody types with minimized cross-contamination risk.
- Protein ligand designed for enhanced protease resistance compared with unmodified protein A leads to lower ligand leakage.
- Meets industrial demands in terms of comprehensive technical and regulatory support and security of supply.
- Animal-component free raw materials and manufacturing process.
MabSelect SuRe resin properties
This resin for monoclonal antibody (mAb) purification contains a rigid, high-flow agarose matrix that delivers excellent pressure/flow properties. Like many of Cytiva's protein A chromatography resins, MabSelect SuRe™ uses oriented ligand coupling for excellent binding capacity. It exhibits low nonspecific protein binding, thereby decreasing impurity levels in the eluate pool.
Benefits of alkali-tolerant protein A ligand
MabSelect SuRe™ resin features an engineered, alkali-tolerant rProtein A ligand for mAb purification. The ligand provides greater stability than conventional protein A affinity resins in the alkaline conditions used in cleaning-in-place (CIP) and sanitization protocols. The resin can withstand rigorous CIP and sanitization procedures with 0.1 to 0.5 M NaOH. The enhanced alkali stability of this resin 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.
Generic elution conditions for different mAbs
MabSelect SuRe™ resin offers generic elution conditions for different monoclonal antibodies, which is an advantage when designing purification platform processes. This feature is also correlated to the construction of the rProtein A ligand, which has a reduced interaction with the VH3 (Fab) domain present in human antibodies.
