These are Protein A Conjugated Hi-Sur Mag beads with diameter of 1 µm. The magnetic beads are pre-blocked by a layer of BSA before a monolayer of recombinant Protein A covalently coupled to the surface. The monolayer of Protein A makes most of the binding sites sterically available for binding of IgG. Their specific and defined surface allow for efficient capture, separation, and downstream handling. The 1 µm Hi-Sur Mag Protein A Beads have a large surface area, high capacity, efficient magnetic pull, and a slow sedimentation rate during incubation, which make the beads automation friendly.


  • Superior binding capacity
  • Significantly low non-specific binding
  • Comparable performance with Dynabeads® Protein A and Pierce™ Protein A Magnetic Beads


Hi-Sur Mag Protein A Beads have a very wide variety of applications. The applications include immunoprecipitation, assay development, and proteins isolation.

Binding capacity:

  • >90 µg rabbit IgG/mg beads
