Figure 3

Graphical representation of the percentage of tumor-free mice over time in each group of mice immunized with the various DNA constructs. C57BL/6 mice (five per group) were immunized twice via gene gun with 2μg/mouse of pcDNA3-E7, pcDNA3-IL2, pcDNA3-IL2+pcDNA3-E7 or pcDNA3-IL2-E7 at one-week interval. One week after the last vaccination, the vaccinated mice were challenged subcutaneously with 5×104 TC-1 cells/mouse. The mice were monitored for evidence of tumor growth by inspection and palpation twice a week. The data shown here are from one representative experiment of two performed.
