Immunocompetent B6 mice were simultaneously injected intraperitoneally with 5D (p53/N-ras) tumor cells at various doses and a control clone 9.5 (2 × 107) recognizing the HPV16 E7–derived epitope RAHYNIVTF or the wt p53-specific CTL clone 1H11 (2 × 107). On the day of treatment and 7 d later, a subcutaneous injection of 6 × 105 IU rIL-2 (Cetus Corp.) in 50% IFA was given.
