Figure 2.
High expression of either SIY or HEL tumor antigen is insufficient to prevent tumor outgrowth. (A) 5 × 105 A-SIY (n = 4), A-HEL (n = 4), or A-EGFP (n = 4) cells were injected subcutaneously into B6C3 mice. Tumor volume was monitored. Data are representative of at least five independent experiments. (B) Mice were inoculated with A-SIY cells on one flank and A-HEL cells on the contralateral flank (n = 4). Tumor volume was monitored. Data are representative of two independent experiments. (A and B) Error bars show SEM.
