Figure 1

Schematic representation of the Plasmodium vivax circumsporozoite protein (CSP) recombinant antigens. The individual recombinant proteins have the specific individual repeats [yPvCSP-VK210 (n = 19), yPvCSP-VK247 (n = 19), or yPvCSP-P. vivax-like (n = 16)] and the C-terminal (CT) region. For each repeat sequence, the amino acids positions and the histidine tag are indicated. The classic repeat sequence VK210 is represented in yellow, VK247 in green, and P. vivax-like in blue. The yPvCSP-All epitopes merges the repeats of all three allelic variants describe above (n = 6/6/5 repeat sequences of VK210/P. vivax-like/VK247, respectively) and the CT region.
