Fig. 6From: Droplet digital polymerase chain reaction (ddPCR) for the detection of Plasmodium knowlesi and Plasmodium vivaxLinear regression of the ddPCR assay for positive plasmid DNA of Plasmodium knowlesi Plasmepsin (100–0.01 copies/µL). The estimated Pearson correlation coefficient of the plasmid DNA regression curve (y = 0.0013x + 0.0224) is 0.5856 (R2 = 0.343, P < 0.05)Back to article page
