Electrophoretic aqueous two-phase partition of proteins

An electrical field was applied to an aqueous two-phase system. The integration of these techniques in one step is used to improve the partition of biological molecules. Experiments were performed for an individual protein - BSA - and for a mixture of proteins - lysozyme and egg albumin - at different polarities and opposite charges of the biomolecules for the aqueous two-phase system Reppal PES - PEG8000. The separation between those two proteins improved more than two-fold
