Fig. 5. The results of antibody-mediated complement-dependent cytotoxicity to BT474 cells. RC-inactive: the cell viability of inactivated rabbit complement is taken as 100% cell viability; RC: rabbit complement; control denotes the mouse sera before immunization; 1 (day 49), 2 (day 49) and 3 (day 49) denotes the day 49 antisera from mice immunized with vaccine candidates 1, 2 and 3. Data shown are the mean of three independent experiments. ***P < 0.001 vs. control, **P < 0.01 vs. control, *P < 0.05 vs. control.
