摘要：
Recombinant human stem cell factor (rhSCF) was produced as an inclusion body by Escherichia coli DH5α grown in a 5 l fermentor. Inclusion bodies of rhSCF were purified and solubilized in urea solution, then renatured with simultaneous purification using a high performance hydrophobic interaction chromatographic (HPHIC) squat column. The refolded rhSCF had a purity of 94% and a bioactivity of 1.2 × 106 IU mg−1of rhSCF protein. The method described is fast and simple to implement.
