General description

Capacity of HiTrap rProtein A for some monoclonal antibodies. Running conditions: Binding buffer: 20 mM sodium phosphate (incl. 3 M NaCl for IgG), pH 7.0. Elution buffer: 0.1 M sodium citrate, pH 3.0.
HiTrap® rProtein A FF columns are prepacked with rProtein A Sepharose™ Fast FLow for purification and fractionation of IgG subclasses and IgG from different sources, including cell supernatants and ascites.
pH below 3 is sometimes required to elute strongly bound IgG species. However, protein ligands may hydrolyze at very low pH.

Application

The recombinant Protein A ligand (produced in E. coli) is coupled to Sepharose™ Fast FLow by a technique which generates a stable thioether linkage between rProtein A and the base matrix. The coupling technique is optimized to give high binding capacity for IgG.

Features and Benefits

  • Quick, convenient preparative purification of monoclonal antibodies.
  • Well-established Protein A-based medium used in many approved MAb processes.
  • Recombinant Protein A exhibits similar Fc region specificity to that of native Protein A but shows enhanced binding capacity and fewer regulatory concerns due to the total absence of mammalian culture in the ligand production and purification.
  • Simple operations with a syringe, pump, or high-performance chromatography system, such as ÄKTA® design.
