Solvent properties critically influence protein separation in hydrophobic interaction chromatography (HIC). This review details how cosolvents affect protein binding and elution, aiding complex mixture resolution.

Area of Science:

  • Biochemistry
  • Chromatography
  • Analytical Chemistry

Background:

  • Hydrophobic interaction chromatography (HIC) separates proteins based on their hydrophobicity.
  • Solvents are crucial for modulating protein-solvent interactions and surface tension in HIC.

Purpose of the Study:

  • To review solvent properties influencing protein binding and elution in HIC.
  • To discuss cosolvents that facilitate protein separation.
  • To present examples of HIC solvent manipulation for complex protein mixtures.

Main Methods:

  • Review of literature on solvent properties in HIC.
  • Analysis of protein-solvent interactions and surface tension effects.
  • Examination of various cosolvents and their impact on protein binding/elution.

Main Results:

  • Solvent properties, including protein-solvent interactions and surface tension, dictate HIC outcomes.
  • Specific cosolvents have been identified to enhance protein binding or elution.
  • Strategic solvent manipulation can resolve intricate protein mixtures.

Conclusions:

  • Understanding solvent properties is key to optimizing HIC for protein separation.
  • Cosolvents offer tunable control over protein retention and elution in HIC.
  • HIC, with informed solvent selection, is a powerful tool for analyzing complex protein samples.
