Figure 3: Protein adsorption on Fe-alginate films. The amount of total adsorbed serum proteins was quantified using a BCA protein assay kit (a). Adsorbed serum vitronectin was evaluated by immunoblotting (b). The relative amount of adsorbed vitronectin was normalized relative to that adsorbed on high-G Fe-alginate. Error bars indicate standard deviation for .
