Lepta DEAE is a weak anion-exchange chromatography resin that takes advantage of differences in the nature and magnitude of charges of different molecules under specific conditions to separate them. This chromatographic resin can be used successfully for the separation and purification of various biological molecules such as recombinant proteins, antibodies, nucleic acids, viruses and virus-like particles, and polysaccharides.

Compared with traditional weak anion-exchange chromatography resin, Lepta DEAE shows better performance:

  1. The improved Lepta base frame is more rigid, so it can achieve a higher process flow rate at lower back pressure and improve process efficiency.
  2. There is an increase in the dynamic binding capacity of the chromatography resin by upgrading the ligand coupling method.
