在这项工作中,通过使用新的基于生物相容性和自缓冲性的Good's缓冲离子液体(GBIL)的水性双相系统(ABS),从水溶液中提取了具有活性构型的模型酶α-胰凝乳蛋白酶。这些新的基于GBIL的ABS的实验液-液相边界数据在298.2 K下进行测量。这些新的离子液体是从生物Good's缓冲液作为阴离子和四烷基铵作为阳离子衍生而来的。这些GBIL的缓冲潜力通过测量其pH值和质子化常数(p K a)在不同温度下通过电位法在水溶液中溶解)。而且,与相应的Good's缓冲液相比,这些GBIL对α-胰凝乳蛋白酶的活性提供了更大的稳定作用。因此,新的自缓冲GBIL不仅可以用作酶学研究的生物相容性介质,而且可以避免使用外部缓冲剂,而在使用传统的基于ILs的介质中,pH调节通常需要外部缓冲剂。因此,这些新的生物相容性GBIL比传统的基于ILs的酶学研究介质更具优势。
