An Overview of Theoretical Developments for Protein Partitioning in Aqueous Two-Phase Polymer Systems

  • Jesse N. Baskir
  • T. Alan Hatton


Theories of protein partitioning in two-phase systems which account for the effects of different aspects of system composition — such as the choice of materials, protein size, polymer molecular weight, polymer concentration, salt concentration, and affinity ligands — are reviewed. Although the present theories provide some information about specific aspects of partitioning, a comprehensive and fundamental theory which can be used to predict protein partitioning behaviour has not yet been developed. Some recommendations for future work are given.
