Effect of T-cell epitope on antibody levels iduced in mice by NANP and NANP T-cell epitope conjugates
Conj. no. | Conjugate | Chains/BSA (avg.) | Bleeding after last injection | IgG anti-CSP, EU | |
Second inj. | Third inj. | ||||
4 | NANP4-C/BSA | 8 | 1 week | 16 | 152 |
4 | NANP4-C/BSA | 8 | 3 months | 14 | 109 |
18 | NANP4-Tcell-C/BSA | 6 | 1 week | 10 | 71 |
18 | NANP4-Tcell-C/BSA | 6 | 3 months | 5 | 12 |
Mice were injected two or three times, at 2-week intervals with 2.5-μg of peptide as a conjugate, and bled 1 week after the last injection: 152 vs. 71, P = 0.01; 109 vs. 12, P < 0.001; 71 vs. 12, P = 0.001.
