Table 1.

Results for volume fraction of water (ϕ^w), fixed charge density (FCD) and glycosaminoglycan (GAG) content for bovine lumbar AF and NP tissues. Values were determined at room temperature (23.8 ± 0.24 °C). For each group, n=15. For all measures, AF < NP (P<0.05).

	AF	NP
ϕ^w	0.81 ± 0.054	0.93 ± 0.022
FCD (mEq / g wet tissue)	0.060 ± 0.027	0.19 ± 0.039
GAG per dry weight (µg / mg)	54 ± 41	490 ± 64
