Protein A chromatography resin with very high dynamic binding capacity at extended residence times, developed for high-titer antibody purification.

MabSelect SuRe LX 是一种蛋白 A 亲和树脂,在延长的停留时间内具有非常高的动态结合能力。该层析树脂专为处理高滴度的单克隆抗体而开发。

新型耐碱 rProtein A 配体可承受 0.1 至 0.5 M NaOH 的严格就地清洁和消毒程序。
用于高滴度培养的高动态结合容量 (DBC) 减少了处理时间和树脂用量。
耐碱、高容量和低配体泄漏与刚性基础基质相结合,使 MabSelect SuRe LX 成为临床应用单克隆抗体纯化的绝佳选择。

MabSelect 蛋白 A 树脂家族的一部分
MabSelect SuRe LX 是蛋白 A 树脂 MabSelect 家族的成员,用于以工艺规模捕获单克隆抗体。 MabSelect SuRe LX 具有 MabSelect 和 MabSelect SuRe 的特性和优势,例如确保出色的压力/流动特性的刚性、高流速琼脂糖基质、导致洗脱液池中杂质水平低的非特异性结合以及定向配体偶联以实现出色的结合能力。它还具有与 MabSelect SuRe 相同的耐碱 rProtein A 配体。在原位清洁 (CIP) 和消毒方案中使用的碱性条件下,这种蛋白质配体比传统的基于蛋白质 A 的树脂具有更高的稳定性。

MabSelect SuRe LX 增强的碱稳定性提高了工艺经济性和产品质量;可以使用具有成本效益的试剂(例如氢氧化钠)进行清洁,从而无需使用昂贵且危险的清洁剂(例如 Gua-HCl)。 MabSelect SuRe LX 增加的动态结合能力也提高了工艺经济性。

与 MabSelect SuRe 一样,MabSelect SuRe LX 的新型配体结构已被证明对蛋白酶具有更高的稳定性。因此,在洗脱过程中 MabSelect SuRe LX 配体的泄漏水平很低。

MabSelect SuRe 已被证明可以为不同的单克隆抗体提供通用的洗脱条件,这些条件也适用于 MabSelect SuRe LX,因为它使用相同的配体。这是设计通用纯化平台流程时的优势。该特征还与 MabSelect SuRe 蛋白配体的构建相关。

MabSelect SuRe LX is a protein A affinity resin with very high dynamic binding capacity at extended residence times. The chromatography resin is developed for processing of monoclonal antibodies at high titers.

  • Novel, alkali-tolerant rProtein A ligand withstands rigorous clean-in-place and sanitization procedures with 0.1 to 0.5 M NaOH.
  • High dynamic binding capacity (DBC) for high titer cultures reduces process time and amount of resin used.
  • Fulfills industrial demands for security of supply, robust performance, and regulatory support.

Excellent for antibody purification in bioprocess applications

Alkali tolerance, high capacity and low ligand leakage in combination with the rigid base matrix makes MabSelect SuRe LX an excellent choice for purification of monoclonal antibodies for clinical applications.

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.
