the dye procion yellow he-3g was bound to dextran of molecular weight 70,000 and the partitioning of this dye-polymer within an aqueous two-phase system containing dextran and poly ( ethylene glycol ) was studied as function of ligand density , polymer concentration , type of salt , concentration of salt and concentration of dye-dextran .
