THE INFLUENCE OF VERTEX POTENTIAL AND MULTIPLE SCAN VOLTAMMETRY ON THE FORMATION OF 8-OXOGUANINE
Original language description
The electrochemical behavior of guanosine (Guo) and guanosine-5´-monophosphate (GMP) at pencil graphite electrode (PeGE) in the phosphate-acetic buffer is examined by cyclic voltammetry (CV). The oxidation peaks of both compounds appear at 1.1 V naturally, but using a multiple cycle we observed an additional peak. It was found that this peak corresponds to oxidation of 8-oxo-7,8-dihydroguanine (8-oG). To determine the potential of 8-oG formation we changed positive vertex potentials in the range from 0.9 to 1.4 V vs. Ag/AgCl/3MKCl reference electrode. The lowest vertex potential at which the 8-oG provided response corresponds to 1.3V for both Guo and GMP (pH 4.16). The most important is the fact that the appearance of the 8-oG peak always occurs afterthe first cycle of CV.
