细胞色素c（cyt.c）经聚环氧乙烷（PEO）链修饰后，可溶于1-乙基-3-甲基咪唑双（三氟甲磺酰基）酰亚胺离子液体中而不变性。然而，由于溶液中充满了离子，合适的支持电解质（KCl）是必不可少的电子转移反应的cyt.c在离子液体中，以获得足够的离子大小的活性中心。
Modification of cytochrome c (cyt.c) by poly(ethylene oxide) (PEO) chains enabled the protein soluble in 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ionic liquid without denaturation. However, as the solution was full of ions, suitable supporting electrolyte (KCl) was essential for the electron transfer reaction of cyt.c in the ionic liquid to attain adequate ion size for the active center.
