PROCESS FOR THE ENRICHMENT OF PROTEINS USING POLYETHYLENE-IMINE

Proteins can be enriched and/or purified by use of polyethylene imines (I) as precipitants. Pref., I have mol. wt 600-100,000. Protein pptn. occurs at low salt concns. and pH 5.0-9.0. At high salt concn. proteins remain in soln., and other contaminants, e.g. nucleic acids are selectively pptd.
