Abstract:
:The partition behavior of proteins, nucleic acids, cell membranes, cell organelles and whole cells has been studied in liquid-liquid two-phase systems composed of water, poly-(ethylene glycol), and an hydroxypropyl starch. The properties of the systems are in many respects comparable with the traditional poly(ethylene glycol)-dextran systems, but the cost is reduced to around one-fifth.
