The formal reduction potential (Eo') of Lumbricus terrestris hemoglobin was determined using thin layer spectroelectrochemistry as 0.073 (+/-0.005) V vs Ag/AgCl (0.281 V vs SHE, standard hydrogen electrode). Nernst plots of Lumbricus terrestris hemoglobin with tris-bipyridinecobalt(II) as a mediator titrant have similar linear slopes as Nernst plots of horse heart myoglobin with hexaamineruthenium(II) as a mediator titrant.
