Figure 2. Heparinization of PGANB hydrogels.

Figure 2.

(A) Schematic of iEDDA click reaction between Hep-Tz and PGANB. Inlet image represents the DMMB qualitative assay to verify immobilization of heparin within the PGANB_Hep hydrogels. (B) UV-Vis spectra of PGANB_Hep before and after reaction with PGANB. (C) Stiffness of 5 wt% PGANB or PGANB_Hep hydrogels crosslinked by different crosslinkers. PEG8NB was sued as control. (D) Effect of heparinization on growth factor absorption.
