Protein G Magnetic Beads

Protein G Magnetic Beads

G-Biosciences' Protein G Magnetic Beads are Fe3O4 beads coated with dextran to produce highly uniform, 1µm beads. Recombinant Protein G is covalently coupled to the dextran coat to produce an enhanced alternative to agarose slurries for immunoprecipitation experiments. G-Biosciences magnetic beads compare well to leading magnetic beads (Figures 2 & 3).

 

The use of magentic beads offers several distinct advantages of traditional immunoprecipitation experiments include a significant reduction in time and non-specific protein binding.

 

A simple protocol involves the addition of your antibody of choice to the beads, which bind the Fc region (See Table 1) during a short incubation. The tube is placed on a magnet and the supernatant is removed by aspiration. The antibody bound magnetic beads can be used in a variety of downstream processes including:

  • Immunoprecipitations
  • Co-immunoprecipitations
  • Chromatin immunoprecipitation (ChIP)
  • Small-scale IgG Purification and antibody labeling
  • Protein Isolation
