Figure 2.

In vitro protein adsorption to PEG, PEG-RGD, and PEG-RDG hydrogels following a two-hour incubation in fetal bovine serum assessed by total protein mass (a) and protein signature (b). The latter is visualized via silver stained SDS-PAGE. Molecular weight ladders were run on both sides of the gel. Data are presented as mean with standard deviation as error bars (n=3).
