Abstract
Partition coefficients in biphasic mixtures of poly(ethylene glycol) and Dextran are compared to cell surface energies obtained from contact angles of each liquid phase on cell layers. Linear relationships are observed between these two independent measurements for a variety of bacterial cells. The results demonstrate the importance of interfacial phenomena and contact angles in the phase-partition process.
摘要
将聚乙二醇和葡聚糖双相混合物中的分配系数与通过各液相在细胞层上的接触角获得的细胞表面能进行比较。对于多种细菌细胞，在这两种独立测量之间观察到线性关系。结果证明了界面现象和接触角在相分配过程中的重要性。
