• Selective Transport of Water-Soluble Proteins from Aqueous to Ionic Liquid Phase via a Temperature-Sensitive Phase Change of These Mixtures

  Mixtures of some ionic liquids (ILs) and water show reversible phase change between a homogeneous mixture and phase-separated state by a small change in temperature. Some water-soluble proteins have been migrated from the aqueous to the IL phase. When tetrabutylphosphonium 2,4,6-trimethylbenzenesulfonate was used as an IL, cytochrome c (Cyt.c) was found to be extracted from the water phase to the IL phase. Conversely, both horseradish peroxidase (HRP) and azurin remained in the aqueous phase. This selective extraction was comprehended to be due to the difference in solubility of these proteins in both phases. The separated aqueous phase contained a small amount of IL, which induced the salting-out of Cyt.c. On the other hand, condensed IL phase promoted the salting-in of Cyt.c. As a result, Cyt.c was preferably dissolved in the hydrated IL phase rather than aqueous phase. In the case of HRP, there was only a salting-out profile upon increasing the concentration of IL, which induced selective dissolution of HRP in the aqueous phase. These results clearly suggest that the profile of salting-out and salting-in for proteins is the key factor to facilitate the selective extraction of proteins from aqueous to the IL phase.

  某些离子液体（IL）和水的混合物在温度发生微小变化时，会在均相混合物和相分离状态之间发生可逆相变。一些水溶性蛋白质已从水相迁移到离子液体相中。当使用 2,4,6-三甲基苯磺酸四丁基鏻作为惰性相时，发现细胞色素 c（Cyt.c）从水相被提取到惰性相中。相反，辣根过氧化物酶（HRP）和天青素都留在水相中。这种选择性萃取被认为是由于这些蛋白质在两种相中的溶解度不同造成的。因此，Cyt.c 最好溶解在水合 IL 相而不是水相中。就 HRP 而言，在增加 IL 浓度时，只出现了盐析出曲线，这导致 HRP 选择性地溶解在水相中。这些结果清楚地表明，蛋白质的盐析出和盐析入曲线是促进蛋白质从水相选择性萃取到 IL 相的关键因素。
