Figure 4: A cytotoxicity study in different cell lines using two concentrations of IN-I-PpoI. Cell viabilities measured by a luminescent cell viability assay are shown as percentages of the wt IN control vector-transduced cells (mean ± SD) after a vector dose of 2 ng (a) and a vector dose of 10 ng (b) of p24. The bars represent viability after LVV mediated I-PpoI protein transduction at different time points post transduction (1, 2, 3 and 6 days, from left to right). Results were analyzed with two-way ANOVA and the Tukey’s multiple comparisons test. ; to ; to .
