title: Influence of bovine immunoglobulin G on faradaic reactions at electrodes.
abstract: The effect of bovine immunoglobulin G (IgG), adsorbed on different electrode materials, on faradaic reactions of hexacyanoferrate(III)-hexacyanoferrate(II), hydroquinone-benzoquinone, nicotinamide adenine dinucleotide, reduced from (NADH), and phenol is described and discussed. The reactions are partially inhibited by IgG, but the current and peak potentials reach protein-independent values for higher concentrations of IgG. The hydroquinone-benzoquinone couple can be used for detection purposes at IgG-covered electrodes in electrochemical immunoassays.
