Refolding protein
WebDec 9, 1997 · In the first, the refolding yield was measured as a function of the time of incubation in glycerol, where the time of the subsequent aqueous activity assay was constant. The results obtained, shown in Table 2, reveal that the longer the incubation in glycerol, the higher the refolding yield. WebRefolding Methods Dialysis, dilution and ultrafiltration- These three methods are traditional and generally used in the protein refolding. The recovery rate is very low and it is difficult to be separated from hybrid proteins. Dilution method is time-consuming and easy to form aggregates of inactive proteins, not suitable for industrial production.
