AMA1 amino acid polymorphic sites in the 14 parasite clones. The AMA1 amino acid polymorphic sites of 14 parasite clones used in this study are shown (the 3D7 sequence was used as a reference). For each parasite, the AMA1 population number (Pop 1 to 6) and whether it was used for immunization (Immu) are shown. The arrow indicates the cleavage site from the 83-kDa form of AMA1 to the 66-kDa form.
