Additive blocking of invasion. Antibodies, either separately or in combinations, were tested for inhibition of parasite invasion into erythrocytes in a one-cycle growth inhibition assay. Anti-GST antibody was used as a negative control (for concentrations of IgGs, refer to Results). The error bars represent the standard deviations of the means of the three independent experiments. One-way ANOVA was performed (P < 0.001) and followed by Bonferroni's pairwise multiple-comparison tests to compare each experimental group. Statistical significance between other groups was not tested.
