These magnetic beads have a surface coated with Protein G.  Magnetic silica beads coated with protein G can be used to detect or isolate target proteins by coupling the Fc domain of an IgG antibody to a target protein.  They are ideal for IgG purification and immunoprecipitation. Other applications include capture of immunoglobulins, purification purposes, antibody screening, protein interaction studies, phage display, immunoassays, and cell isolation. 

Protein A and Protein G bind to Fc regions of immunoglobulins. After binding onto magnetic beads with a coating protein A or Protein G, immobilized immunoglobulins can be used for immunoprecipitation of various biomolecules, or can be eluted in a native or denatured state.


  • High quality recombinant Protein G covalently bound to the particle surface
  • Ideal for IgG purification and immunoprecipitation
  • Recombinant protein G (~26 kDa) was produced by removing albumin, cell wall and cell membrane binding domains from wild-type protein G
  • Concentration of 10mg/ml


  • IgG purification
  • Immunoprecipitation
  • High yield protein purification
  • High yield antibody isolation


  • Magnetic Silica Beads coated with Protein G, 600nm bead size, 1ml
