Background:

  • Large-scale production of recombinant human monoclonal antibodies requires cost-effective, high-throughput purification methods.
  • Traditional purification often utilizes Q-packed-bed columns, which can present throughput limitations.

Purpose of the Study:

  • To evaluate Q membrane adsorbers as a scalable and economical alternative to Q-packed-bed columns for antibody purification.
  • To review the scientific principles and applications of Q membrane technology in bioprocessing.

Main Methods:

  • Review of Q membrane chromatography principles and applications.
  • Evaluation of Q membrane adsorbers in a flow-through mode for process-scale antibody production.
  • Comparison with traditional Q-packed-bed column chromatography.
