TLS by ApPolη past 5R-Tg, 5S-Tg, and 8-oxoG. Increasing amounts of ApPolη (12, 24, 59, 118, 588 fmol in lanes 3–7, resp.) were incubated with 40 nM of the primer-templates indicated beside each panel. The templates contained 5R-Tg (a), 5S-Tg (b), undamaged G (c), and 8-oxoG (d). The samples for lanes 1 and 2 contained 0.1 U T7 DNA polymerase and no enzyme, respectively. The reactions were incubated at 3 7 C for 20 minutes, and then were subjected to 15% polyacrylamide/7.5 M urea gel electrophoresis. The autoradiograms of the gels are shown.
