Figure 4From: Shift in epitope dominance of IgM and IgG responses to Plasmodium falciparum MSP1 block 4IgG subclass distribution of MSP1 Block 4 and Block 16-17. Sera from samples that contained antibodies to one or more Block 4 peptides (left panel) or Blocks 16-17 (right panel) were assayed for IgG1 and IgG3 isotypes. Colombia (n = 21), Papua New Guinea (n = 9), and Cameroon (n = 11). Clustering of isotype distribution is indicated by ellipses.Back to article page
