| Description | First use of a pyrolytic graphite electrode (PGE) for electroreduction of DNA bases PGE offers DNA redox signals analogous to those of mercury-based electrodes. Novel analytically applicable redox signals of DNA bases were found. Distinct cathodic signals of A, C, G, T, mC or U can be measured at the PGE. Cathodic polarization can selectively switch off DNA anodic signals and vice versa. |
