These are Protein A Conjugated Mono Mag beads with diameter of 3 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 3 µm Mono Mag Protein A Beads have high capacity, efficient magnetic pull, and a slow sedimentation rate during incubation, which make the beads automation friendly.


  • Narrow size distribution, CV≤5%
  • Significantly low non-specific binding
  • Fast magnetic separation


Mono Mag Protein A Beads have a very wide variety of applications. The applications include assay development and proteins isolation or immunoprecipitation.
