[Effect of calcium ions on plasma membrane structure].
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.
