Figure 3.
Effect of the applied potential on the adsorption kinetic of 0.10 mg·mL−1 BSA and BSA cross-linked with DSS after adsorption of the respective protein monolayer onto OTCE at OCP. Experiments were performed in 10 mmol·L−1 citrate at IEP and a flow rate of 1 mL·min−1. The arrow shows the time which the external potential was applied.
