Figure 9. Effects of anti-sera on tumor cell viability.

Figure 9

(A) The effects of pooled pre-immune serum and antiserum derived from mice immunized with βhCG-TT or βhCG-TT + MIP on the viability of SP2/O and B16F10 cells. Bars represent arithmetic mean ± standard error. *p≤0.05, **p≤0.01, ***p≤0.001 versus pre-immune serum. (B) Effect of co-incubation with hCG (1 µg/ml) on the loss of viability of SP2/O cells induced by antiserum from mice immunized with βhCG-TT or βhCG-TT + MIP. Bars represent arithmetic mean ± standard error. *p≤0.05, **p≤0.01versus serum alone.
