This procedure allows us to previously identify well-known and new malaria antigens including protein disulfide isomerase (PDI), the HSPA5 member of the heat shock protein-70 family (also called binding immunoglobulin protein BiP), the aspartic proteinase plasmepsin, and the eukaryotic translation initiation factor 3 (IF3) as antigenic proteins [21]. Here, HSPA5 is linked to malaria.
