Fig. 1From: In vitro invasion inhibition assay using antibodies against Plasmodium knowlesi Duffy binding protein alpha and apical membrane antigen protein 1 in human erythrocyte-adapted P. knowlesi A1-H.1 strainSchematic structure of PkDBPα and PkAMA1 protein expression. a Schematic of PkDBPα region II (200–536 aa) and PkAMA1 domain I and II (43–387 aa). b Reduced (+) and non-reduced (−) condition of refolded-PkDBPα and PkAMA1 (2.5 and 5 µg for BSA were loaded per well). c Western blot analysis of recombinant proteins PkDBPα and PkAMA1, and PkA1-H.1 parasite lysate probed with antibodies. His anti-His antibody, R rabbit antibodies, U uninfected RBCs, P parasite lysate. Black head arrows, specific fragmentation bandsBack to article page
