Observed time constants (tau) and halflife data (t _1/2) for heparan sulfate growth on endothelial surface

Treatment group	τa (h)	t b1/2 (h)
15 dyn/cm2	18.9 ± 10.2	13.1
15 dyn/cm2 + HpaseIII	11.8 ± 3.2	8.2
0 dyn/cm2 + HpaseIII	20.2 ± 0.4	13.9

^aValues are ± fit error

^bHalflife values are calculated from t _1/2 = τ/ln(2)
