A number of lines of evidence suggested early on that 8-oxo-7,8-dihydrogua-nine (8G) is more readily oxidized than guanine [42, 86-88]. The most direct evidence in this regard was the ability to detect 8G selectively using electrochemical detectors in liquid chromatography [89]. We therefore suspected that 8G would react with metal complexes with potentials lower than... [Pg.176]

Figure 2.5 Solid Phase DNA Synthesis Cycle (Contd.). Most frequently used base protecting groups are shown Bz Af-6 benzoyl (adenine), W-4 benzoyl (cytosine) N-2 isobutyroyl (guanine). All are base sensitive. DNA chain is built up from 3 to 5 on controlled-pore glass (CPG) bead solid support. Post global deprotection and resin removal, the desired product oligo-/polydeoxynucleotide is then separated initially by precipitation by means of an agent such as ethanol and purified finally by reversed phase liquid chromatography, or ion exchange chromatography as appropriate (see later in Chapter 2).
