Figure 12From: Mutational analysis of highly conserved aspartate residues essential to the catalytic core of the piggyBac transposaseRelative frequency of excision obtained with the REN colony screen. Positive control, wild-type piggyBac, is set to 100. Data are expressed as a mean of three replicates +/- standard error bars. ANOVA test was performed using GraphPad Prism 3.0 software. Means were considered statistically significant when p-values less than 0.05 were obtained with the Dunnett's post-test. Statistical significance of difference with regards to positive control is indicated on all data figures as asterisks above bars. (p < 0.05)Back to article page
