%X A method was developed to increase the recovery of recombinant human stem cell factor (rhSCF) from inclusion bodies using high performance hydrophobic interaction chromatography (HPHIC). The target protein was first solubilized in 8.0 mol/L urea solution, and was purified and refolded simultaneously by HPHIC with different chromatographic cakes. Experimental conditions, such as the ligand structures of stationary phase and the composition of mobile phase, were optimized. Under the optimal conditions, high mass recoveries and specific activities of rhSCF were acquired, the purities of rhSCF were above 95.5%, and the mass recoveries of rhSCF were above 49.6%. The final product was also verified as monomer by size exclusion chromatography and matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). These results provided further evidence that HPHIC is an effective tool in the refolding and purification of recombinant proteins.
