Figure 1: Average tumor volume (a) and percentage of tumor-free C57/BL6 mice (b) at week five after C3 tumor challenge. Mice were either nonvaccinated (PBS control) or vaccinated either with DPX-E7 or CE-based vaccine as outlined in methods, after 6 days of tumor implantation. Tumor measurements were carried out every 3-4 days and tumor volume was calculated. Data represents mean ± SDM from at least 8–10 mice per group and from one of three independent experiments with similar findings.
