Abstract
The structure of thymocyte's plasma membranes was studied as affected by calcium ions (0-1.126 mM). The fluorescence intensity of 1-anilinonaphthalene-8-sulphonate, the epimerization degree of pyrene and fluorescence anisotropy of membrane proteins were studied. The change of electrochemical properties of membranes, conformation of membrane proteins and lipid fluidity has been shown.
摘要
研究了钙离子（0 - 1.126 mM）对胸腺细胞质膜结构的影响。研究了1-苯胺基萘-8-磺酸盐的荧光强度、芘的差向异构化程度以及膜蛋白的荧光各向异性。结果表明，膜的电化学性质、膜蛋白构象和脂质流动性发生了变化。
