title: Separation and identification of different refolding components.
abstract: A dual-gradient ion-exchange chromatography (IEC) refolding process has been successfully applied to renature lysozyme at high concentration. The different refolding components were separated by size-exclusion chromatography with low concentrations of urea and NaCl added into elution buffer. The hydrodynamic characteristics during separation and the hydrophobic properties of these components were also tested.
