Kinetics of hydrogel erosion and dextran and VEGF release. (a) Cumulative release curves of 20 kD dextran from MITCH-PEG into bulk PBS medium. Solid lines represent curve-fits for Fick's 2nd law of diffusion from thin slabs. (b) Cumulative fraction of hydrogel material eroded into bulk PBS medium. (c) Quantification of VEGF165 cumulative release by ELISA.
