Concentrations of a HRP2, b p-LDH and c Aldolase detected by multiplex bead assay plotted against serial dilutions of 3D7, Dd2, HB3 and 3BD5. No HRP2 was detected for 3BD5 irrespective of parasite density. Note: y-axis is a log scale and antigen concentrations of 0.00 ng/mL are indicated on the chart as 0.01 ng/mL to allow for plotting
