4-aminophthalimide (API), covalently attached to nucleotide (dCTP or dATP) has recently beendesigned as a fluorescent label for the detection of DNA-protein interaction. However API is electrochemically reducible and therefore it is possible to use alternatively the API-modified nuclotides as DNA redox labels. The electrochemical behavior of labeled nucleotides and labeled DNA was studied using cyclic voltammetry and transfer stripping cyclic voltammetry at hanging mercury drop electrode. Observed CVs showed irreversible reduction signals of 4-aminophthalimide label without production of consequently oxidizable/reducible species.
