Effects of two salt additives, NaCl and NaClO4, at the fixed concentrations of 0.215?M on the properties of aqueous two-phase systems (ATPSs) formed by dextran (Dex) and polyethylene glycol (PEG), and the effects of NaClO4 at the same concentration on the properties of ATPS formed by PEG and Na2SO4 were examined. The effects of these salt additives on partitioning of 12 small organic compounds and five proteins in the above ATPSs were studied. In each system with a given salt additive, 0.5?M sorbitol, 0.5?M sucrose, and 0.5?M and 1.5?M trimethylamine N-oxide (TMAO) were also used as additives. ...
