Why doesn't a redox active protein become oxidized/reduced during electrophoresis, i.e. when it is run on a PAGE gel?

I work with metalloenzymes with reasonable reduction potentials, between -0.1 and +0.4 V vs. NHE, that I constantly run on native PAGE gels. I've noticed they don't change color during...
