CCC with Polymer Phase Systems

Separation of proteins requires the use of aqueous-aqueous polymer phase systems to prevent de-naturation of the analytes by organic solvents. Figure 13 shows separation of four stable proteins by a polymer phase system composed of 12.5% (w/w) polyethylene glycol 1000 and 12.5% (w/w) dibasic potassium phosphate. The separation was performed by a cross-axis coil planet centrifuge (hybrid between Type L and X in Figure 2). The method has also been successfully applied for purification of recombinant enzymes.
