| Abstract: | Structural changes in red blood cell (RBC) membrane are investigated by fluorescence techniques. Results obtained with three probes (DPH, 3-PM and fluorescamine) indicate a significant increase in membrane rigidity associated with aging of RBCs. Discrepancies between our observations and published data could arise from utilization of experimental conditions closer to physiological conditions in our study. Use of intact RBCs continuously manipulated in a 37 degrees C environment could represent experimental conditions favourable to the identification of rheologic membrane changes in senescent RBCs. |
