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.
