The levels of anti-SLA specific IgG1 (A), IgG2a (B), and IgG (C) antibodies based on mean absorbance in sera of BALB/c mice after challenge. Mice immunized SC, three times in 3-week intervals, with SLA, ISCOMATRIX EPC, ISCOMATRIX DSPC and ISCOMATRIX DMPC, or buffer alone. Blood samples were collected from the mice 6 weeks after challenge. The assays were performed using ELISA method in triplicate at 200, 2000, 20,000 or 200,000-fold dilution for each serum sample. Values are the mean±SD
