Effect of salt-based adjuvant on partition behaviour of protein in aqueous two-phase systems composed of polypropylene glycol and cholinium glycinate

Aqueous two-phase systems (ATPSs) composed of ionic liquids (ILs) have been widely explored over the past decade for application in protein purification. The interaction between the phase components of ATPSs and the target protein is one of the factors governing the partition behaviour of the protein. The addition of adjuvants like inorganic salts at a low concentration in an ATPS could manipulate the partitioning of the protein between phases....
