Cure of M-3 micrometastases-bearing mice with four peptides and polycations as adjuvant. Peptides were used as described in Fig. 2. The following amounts of polycations were used per 100 μg of peptide mix: pLys16, 37.5 μg; fpLys200, pLys240, pLys450, and pArg720, 7.5 μg. Ten animals per group were treated in a and b, and eight animals were treated in the groups of c.
