The addition of packing material for high performance hydrophobic interaction chromatograghy (HPHIC) into the denaturant solution to prevent, or depress protein aggregation in the denatuaration process is presented. The renaturation of α-chymotrypsin (α-Chy) denatured with guanidine hydrochloride (GuHCl) solution indicated that renaturation efficiency can be enhanced from 36.1% to 59.0% by this new method. The structure of the ligand linking of HPHIC packings is also important for the protein renaturation.
