Protein A Super Mag (150 nm) are protein A conjugated magnetic beads with average particle size of 50 nm. The monolayer of protein A that is covalently coupled to their surface makes most of the binding sites sterically available for binding of IgG. With large surface area, excellent colloidal stability and unique surface coating, Protein A Super Mag (150 nm) exhibit high binding capacity, low non-specific binding and fast magnetic separation.


  • High binding capacity
  • Significant low non-specific binding to proteins and nucleic acid
  • Fast magnetic separation


Ideal for assay development. Low non-specific binding of proteins and nucleic acids.

Binding capacity:

  • >60 µg rabbit IgG/mg beads
