Abstract: A method is described for isolating an exogenous polypeptide in a non-native conformation from cells, such as an aqueous fermentation broth, in which it is prepared comprising contacting the polypeptide with a chaotropic agent and preferably a reducing agent and with phase-forming species to form multiple aqueous phases, with one of the phases being enriched in the polypeptide and depleted in the biomass solids and nucleic acids originating from the cells. Preferably, the method results in two aqueous phases, with the upper phase being enriched in the polypeptide.
