(a) supF mutant frequencies of plasmid replicated in U2OS cells and (b) mixtures of randomly mutagenized supF (pZ189-RM) and supF+ (pZ189-T_E107K/D402E) plasmids in KS40/pOF105 and RF01. pZ189-RM was mixed with pZ189-T_E107K/D402E at the ratios shown in (b). White and gray bars indicate KS40/pOF105 and RF01, respectively. Data are represented as the means + SD (standard deviation) of three independent experiments. There were no significant differences between RF01 and KS40/pOF105 in all the supF mutant frequencies
