Protein G Sepharose Fast Flow is recombinant protein G coupled to Sepharose 4 Fast Flow resin.

  • High binding capacity: approximately 20 mg human IgG per mL resin
  • Broad-spectrum: binds to a broad range of IgG species and subclasses
  • Complements Protein A resins: unlike protein A, protein G binds all human and mouse IgG subclasses, including human IgG3 and mouse IgG1 as well as all rat IgG subclasses
  • No specific albumin binding: recombinant protein G has been genetically engineered to remove the albumin binding region
  • Minimal leaching: optimized coupling method minimizes leaching of recombinant protein G and improves binding capacity for IgG
  • Wide range of formats: including loose resin packs from 5 mL to 5 L, for manual or automated antibody purification and immunoprecipitation procedures

IgG purification

Protein G Sepharose 4 Fast Flow is a good first choice for general-purpose capture of antibodies at laboratory scale. Compared to protein A-based resins, it binds a broader range of immunoglobulins from eukaryotic species and more classes of IgG.
