Cyclic AMP Detection by Electrode Modified with 17mer Oligopeptide

Abstract
An oligopeptide (17mer) which recognizes cyclic AMP was designed and applied to electrochemical detection of cAMP. Redox peak currents on cyclic voltammograms of ferrocyanide/ferricyanide redox couple with Au electrode which was modified with the peptide showed response dependently on the cAMP concentration, while the electrode showed only slight response to ATP that is a structural analog of cAMP.
