Method for isolating and purifying a protein and resulting protein

摘要

The invention concerns a method for isolating and purifying a protein of interest, in particular from a complex medium such as a plant extract. Said method is characterized in that it compromises a step whereby a complex medium, comprising the solution containing the protein of interest to be purified and a solid support capable of enabling it absorption, is brought in the presence of an agent capable of causing said protein to precipitate in soluble form. The protein of interest is thus partly aggregated and absorbed on the solid support without substantial formation of macro-aggregates in the solution capable of spontaneous elutriation.
