GAG binding on Scl2 hydrogels. (A–B) Binding of fluorescently–labeled (A) HA and (B) heparin to Scl2. Empty wells were used as negative control denoted ‘no material’. (C–D) Release of fluorescently–labeled (C) HA and (D) heparin from Scl2 hydrogels over 1 week. The fluorescence was measured in arbitrary units and relative binding of heparin or HA was normalized to the highest level of fluorescent intensity at each time point to provide the fraction of heparin or HA released over time. Values represent means ± SD. ***p < 0.001 (n = 3).
