Figure 4From: Antibody responses to the merozoite surface protein-1 complex in cerebral malaria patients in IndiaPrevalence of anti-MSP IgG subclasses for the different subunits. The prevalences of the four IgG subclasses are shown. Test samples were considered positive if their OD values were higher than the mean plus two standard deviations of 10 pooled plasmas from malaria naïve donors from North America. The percentage prevalence was then calculated as described in figure 2.Back to article page
