Average Diameters of Human Red Blood Cells and Derived "Ghosts" As Obtained from Dynamic Light Scattering Measurementsa
| cells | treatment | size ± SD (μm) |
|---|---|---|
| RBC | 60 min at 37 °C (no enzyme) | 7.1 ± 0.04 |
| RBC | 60 min at 37 °C (no enzyme), then 2 min, 4 °C | 7.1 ± 0.03 |
| RBC | PlcHR2, 60 min, 37 °C | 5.5 ± 0.03 |
| RBC | PlcHR2, 60 min, 37 °C, then 2 min, 4 °C | 5.6 ± 0.1 |
| "ghosts" | osmotic shock | 1.9 ± 0.1 |

Two different instruments were used, respectively Mastersizer and Nanosizer, for measurements on RBC and "ghosts", in order to use in each case the instrument that suits better the size of the measured object.
