Free diffusion in PBS and relative diffusivity of the five tracers in the bone LCS
| Tracer | Dfree (µm2/s) | Dlcs/Dfreeb |
|---|---|---|
| sodium fluorescein | 540a | 55±9% |
| dextran-3k | 187.7±18.2 | 66±20% |
| dextran-10k | 107.7±5.9 | 0% |
| parvalbumin | 197.0±11.0 | 80±45% |
| ovalbumin | 106.5±14.9 | 61±20% |
a
Notes: The value of free diffusion reported in literature was used to calculate the relative diffusivity for sodium fluorescein [29, 30].
b
Mean values of the free diffusions were used in the calculations of relative diffusivities for the tracers, which were reported as mean ± standard deviation. No significant difference of the relative diffusivity (DLCS/Dfree) was detected among the tracer groups (p > 0.05).
