Refolding of fusion ferritin using gel filtration chromatography |
초록 |
Fusion ferritin(FH+FL), an iron-binding protein, was purified from recombinant E. coli by two-step sonications with urea. Unfolded ferritin was refolded by gel filtration chromatography with various concentration of urea. 50 mM Na-phosphate(pH 7.4) buffers with 2 M to 6 M urea were used in GFC. Objective was to characterize the structure change with urea concentration. Molecular weight was determined using GF-HPLC and RP-HPLC was used to quantify the unfolded and refolded proteins. Also the activiy of ferrin was confirmed by iron-uptake reaction.
