Reversible increase in the redox potential of cytochrome c in methanol.
The E degrees ' of cytochrome c on a self-assembled monolayer (SAM) modified gold electrode increased by 300 mV immediately on immersion in methanol; on re-immersion of the electrode in aqueous buffer, the original faradaic response was restored, but over a period of 120 min, indicating that methanol causes a significant change in conformation/orientation of the protein.
