Lepta SuperA is an affinity chromatography resin for antibody purification, which separates through the specific interaction between antigen and antibody. This chromatography resin is designed to handle high concentrations of monoclonal antibodies. Lepta SuperA has the characteristics of high capacity, high flow rate and alkali resistance. Besides, it is suitable for capturing monoclonal antibodies or Fc-fusion proteins from large volume cell culture media, as well as the capture of polyclonal antibodies from ascites or plasma. Main features are:
(1) It has a high dynamic binding capacity;
(2) The modified alkali-resistant rProtein A ligand can tolerate 0.5–1.0M NaOH for cleaning-in-place (CIP).
