Figure 5From: Rare human papillomavirus 16 E6 variants reveal significant oncogenic potentialModulation of apoptosis by HPV16 E6 variants. Flow cytometry was performed after a 16 h treatment in semisolid medium and apoptosis-alive (Annexin V-FITC+/propidium iodide-), apoptosis-dead (Annexin V-FITC+/propidium iodide+), intact-dead (Annexin V-FITC-/propidium iodide+) and intact-alive (Annexin V-FITC-/propidium iodide-) cells were calculated for each quadrant. (A) dot plots from a representative experiment. (B) Mean values of at least three independent experiments are presented as average (mean) values ± standard deviation (SD). Significance was tested by a one-way ANOVA test. A P value of < 0.05 was considered significant.Back to article page
