Cyclic voltammetry of the recombinant cytochrome c4 which was applied to a freshly polished pyrolytic PGE electrode. The solution contained 10 mM HEPES buffer and 2 M NaCl at pH 7.0. Values obtained (vs. SHE) were Epc1 = 0.26 V, Epc2 = 0.35 V, Epa1 = 0.23 V, Epa2 = 0.34 V and E1/2 = (Epc + Epa)/2 = 0.24 V and 0.34 V.
