Protein purification methods
Key Questions

Answer:
Precipitation
Dialysis
Membrane FiltrationExplanation:
If you know the isoelectric point of the protein you could precipitate and filter or centrifuge the protein fraction by pH adjustment. Proteins are fairly large molecules and dialysis or membrane filtration can be used to remove impurities that will easily pass through the pores of a membrane whilst retaining the protein fraction.
