Magne™ Protein G and Magne™ Protein A Beads are magnetic affinity beads with high specificity and high capacity for purification of immunoglobulins from cell culture media, ascites and serum samples.

These paramagnetic beads are composed of iron encapsulated in macroporous cellulose with low nonspecific binding. The magnetic beads use a novel attachment chemistry to immobilize recombinant Protein G or Protein A protein molecules in the same orientation on the surface of the bead. The oriented attachment is known to improve the functionality of immobilized proteins.

These beads offer a convenient method for achieving high purity and high recovery of monoclonal and polyclonal antibodies from a variety of biological samples. The superb magnetic properties of Magne™ Protein G and Magne™ Protein A Beads allow rapid and efficient capture of antibodies either with manually processed samples or in a high-throughput manner using the Promega ReliaPrep™ LV 32 HSM Instrument or a robotic platform such as the Beckman Coulter Biomek® FX.

Magne™ Protein A and Magne™ Protein G Beads:

  • High purity and rapid, efficient antibody recovery
  • Low nonspecific binding
  • Ease of handling and cost effectiveness
  • High binding capacity1 (≥25mg) of the beads for Protein A and Protein G
  • Optimized performance
