Alteration of erythrocyte membrane fluidity by heavy metal cations.


Fluorescence polarization measurements were carried out on erythrocyte ghosts treated with heavy metal cations. Membranes labelled with the fluorescent lipid probe all-trans 1,6-diphenyl-1,3, 5-hexatriene (DPH) had increased DPH polarization (P) values, consistent with increased membrane lipid viscosity, when treated with 10(-3)-10(-2) M of the chloride… (More)
