This work unfolds functionalized ABSs composed of FILs ([CCIm][CFSO] and [N1112(OH)][CFSO]), mere fluoro-containing ILs ([CCIm][CFSO] and [CCIm][CFSO]), known globular protein stabilizers (sucrose and [N1112(OH)][CFSO]), low-molecular-weight carbohydrate (glucose), and even high-charge density salt (KPO). The ternary phase diagrams were determined, stressing that FILs highly increased the ability for ABS formation. The functionalized ABSs (FILs vs.

Effective single-step aqueous biphasic system (ABS) extraction for the simultaneous purification of IFN-α2b and BSA (serum albumin protein) was developed in this work. Effects of the ionic liquid (IL)-based ABS functionalization, fluorinated ILs (FILs; [C2C1Im][C4F9SO3] and [N1112(OH)][C4F9SO3]) vs.
