Table 1. The characteristics for dextrans of different molecular weights.

Vascular permeability	Interstitial diffusivity	Plasma half-life time
(μm/s)	(μm2/s)	(min)
ω 3.3k = 1.890	D 3.3k = 30.83	τ 3.3k = 7.35
ω 10k = 1.280	D 10k = 17.28	τ 10k = 8.17
ω 70k = 0.392	D 70k = 3.01	τ 70k = 23.77
ω 2M = 0.085	D 2M = 0.26	τ 2M = 35.14
ω 16M = 0.060	D 16M = 0.16	τ 16M = 37.25

The values for 3.3-kDa, 10-kDa, 70-kDa, and 2-MDa dextrans were fitted from Figure 6 of [14] while those for 16-MDa dextran were extrapolated from the former four.
