GenScript Monofinity A Resin

GenScript's Monofinity A Resin™ is made of a novel recombinant protein A ligand that has a high specific binding capacity to the Fc region of immunoglobulin molecules and enhances chemical stability under Cleaning-in-Place (CIP) conditions. Monofinity A Resin™ has several benefits such as high-flow agarose base, low non-specific binding and better dynamic binding capacity than similar products from other major vendors.

Monofinity A Resin™

Protein A affinity chromatography resin is the most commonly applied tool for the isolation and purification of IgG. Protein A is a cell wall component found in several strains of Staphylococcus aureus . It has five high affinity binding sites capable of binding specifically to the Fc region of immunoglobulin molecules from several species. Covalently immobilized Protein A matrices have been extensively used to purify IgG from several species of mammals.

  • Novel Protein A ligand withstands CIP procedures with 0.1 to 0.5 M NaOH
  • Easy CIP, reduces the contamination and impurity level
  • Consistent performance with extremely low ligand leakage
  • Dynamic binding capacity over 30 mg/ml under experimental condition
  • Can be used for commercial manufacture of monoclonal antibodies
  • Significantly reduces overall process costs
