Figure 1. Strong correlation between anti-AMA1 antibody level and the growth-inhibitory activity in AMA1-specific IgGs.

Figure 1

Anti-AMA1(3D7) (A) or anti-AMA1(FVO) (B) antibody levels (µg/ml) in the GIA well (x-axis) are plotted against % inhibition (y-axis) of P. falciparum 3D7 (A) or FVO (B) parasites. Each AMA1-specific IgG was tested at three (for U.S. IgGs) or two (for Mali IgGs) different concentrations. All responses below the limit of detection in ELISA were assigned a value of 2 µg/ml for the analysis.
