bFGF binding to covalently cross-linked PEG hydrogels. Absorbance values reflect the amount of bFGF detected in the hydrogel via a standard ELISA assay. Average values from two experiments are shown for hydrogels containing 21.8 µg of covalently immobilized LMWH (6) and merely passively encapsulated LMWH (7).
