A. Quantitative real-time RT-PCR was used to detect levels of UNG transcript remaining after siRNA transfection in U20S cells. AInline graphic. Western blot analysis of endogenous UNG2 and CENP-A protein levels 48 hours after siRNA transfection in U20S cells. Tubulin was detected as a loading control. AInline graphic. Normalized band intensity for part AInline graphic. B. Quantitative real-time RT-PCR was used to detect levels of UNG transcript remaining after siRNA transfection in HeLa cells. BInline graphic. Western blot analysis of endogenous UNG2 and CENP-A protein levels 24 hours after siRNA transfection in HeLa cells. Histone H3 was detected as a loading control. BInline graphic.
