Multidimensional liquid chromatography (MDLC) combines separation techniques for efficient protein purification. This review explores on-line column coupling and packed columns for improved selectivity and scalability in bioprocessing.

Area of Science:

  • Biochemistry
  • Analytical Chemistry
  • Chemical Engineering

Background:

  • Protein purification is a critical step in biopharmaceutical development.
  • Traditional methods are often labor-intensive, expensive, and difficult to scale.
  • Multi-dimensional separation techniques offer enhanced selectivity and efficiency.

Purpose of the Study:

  • To review the concept and applications of multi-dimensional liquid chromatography (MDLC) for protein purification.
  • To categorize MDLC approaches into two main strategies: collinear and coupled columns.
  • To highlight the potential of MDLC in improving the scalability and cost-effectiveness of protein purification processes.

Main Methods:

  • Review of existing literature on multi-dimensional chromatography.

  • Classification of MDLC systems into two categories: single column with multiple separation mechanisms and on-line coupled columns with different materials.
  • Discussion of selectivity modulation via mobile phase and material selection.

    • Main Results:

    • MDLC systems can be designed using collinear separation mechanisms within a single column or by physically coupling multiple columns.
    • Novel chromatographic packings aim for high selectivity and modulated separation characteristics.
    • On-line coupled columns offer a discrete 2D separation system, particularly attractive for large-scale purification with "on-off" chromatography.

    Conclusions:

    • MDLC techniques, including advanced materials and column coupling, promise significant improvements in protein purification.
    • The development of on-line MDLC systems can streamline complex purification processes, reducing time and cost.
    • MDLC offers a versatile platform for achieving high-purity proteins essential for biopharmaceutical applications.
