Variations in the formal electrochemical potential ( E 0 ) and electron‐transfer rates ( k 0 ) of the blue copper protein azurin have been directly observed. A new method, fluorescent cyclic voltammetry (FCV), was used to resolve the properties of 100–1000 proteins. On this scale, the presence of large variations in the values of both E 0 and k 0 could be established and several forms of heterogeneity were differentiated.
