MabSelect Xtra, with extra high dynamic binding capacity, is a protein A resin developed to meet the demands of increasing levels of expression in monoclonal antibody feedstocks.

比目前可用的蛋白 A 层析树脂具有更高的动态结合能力。
与 MabSelect SuRe 和 MabSelect 相比,压力/流动特性略低。
Resin 满足工业对供应安全性、强大性能和监管支持的需求。
MabSelect Xtra 具有与 MabSelect 相同的重组蛋白 A 配体,但基于高流动性琼脂糖基质,与 MabSelect 相比,具有更高的孔隙率和略微减小的粒径。这导致更高的容量——MabSelect Xtra 对 IgG 的动态结合容量比目前可用的蛋白 A 层析树脂高约 30%。

此外,MabSelect Xtra 对许多 Fc 融合蛋白具有更高的容量。

与其他蛋白 A 树脂相比,MabSelect Xtra 树脂的总体生产成本较低,因为它可以以更少的批次处理浓缩原料。

  • Higher dynamic binding capacity than currently available Protein A chromatography resins.
  • Improved process economics through reduced raw materials costs and/or reduced number of cycles.
  • High purity capture due to high ligand selectivity and matrix hydrophilicity.
  • Slightly lower pressure/flow properties compared to MabSelect SuRe and MabSelect.
  • Resin fulfills industrial demands for security of supply, robust performance, and regulatory support.

Increased porosity

MabSelect Xtra has the same recombinant Protein A ligand as MabSelect but is based on a high-flow agarose base matrix with increased porosity and a slightly decreased particle size compared to MabSelect. This results in higher capacity—MabSelect Xtra has about 30% higher dynamic binding capacity for IgG than currently available Protein A chromatography resins.

In addition, MabSelect Xtra has a higher capacity for many Fc-fusion proteins.

Lower costs

Compared with he other protein A resins, MabSelect Xtra resin provides a lower overall production cost due to the possibility of processing concentrated feedstocks in fewer batches.
