Abstract

We have found out that the phase separation of Triton X-100 micelle solution was caused by the addition of poly(ethylene glycol) (PEG) above a critical concentration. The critical concentration of PEG depended on its molecular weight and temperature, larger molecular weight or higher temperature giving lower critical concentration. These results were analyzed on the basis of the osmoelastic coupling theory recently proposed by us (Biochemistry (1989) 28, 3710-3715; Biochemistry (1989) 28, 5626-5630).

摘要

我们发现，在高于临界浓度时添加聚乙二醇（PEG）会导致Triton X-100胶束溶液发生相分离。PEG的临界浓度取决于其分子量和温度，分子量越大或温度越高，临界浓度越低。基于我们最近提出的渗透弹性耦合理论（《生物化学》（1989年）28卷，3710 - 3715页；《生物化学》（1989年）28卷，5626 - 5630页）对这些结果进行了分析。
