denatured protein concentration and urea concentration
in the renaturation process of recombinant human interferon-γ inclusion body by dilution were studied and at the same time pulse renaturation was tested. The optimum renaturation conditions were obtained. Results showed that urea could suppress the aggregation of protein during the renaturation process and the suitable urea concentration increased with the increase of denatured protein concentration. The activity and specific bioactivity was up to 2.39×105 IU8226;ml-1 and 2.21×107 IU8226;mg-1 respectively under 4 ℃
pH 8.0
1.0 mol8226;L-1 urea
0.1 mg8226;ml-1 protein and pulse renaturation operation mode.
