| Abstract: | The measurements of the fluorescence polarization of perylene embedded in erythrocyte membranes were carried out with normal and reticulocyte-rich blood, and the microviscosity of erythrocyte membranes was calculated from the polarization degree. In intact cells, reticulocyte membranes had a significantly lower microviscosity than normal erythrocyte membranes, while in ghosts no significant difference in membrane microviscosity was observed between reticulocytes and mature erythrocytes. |
