Fig. 5From: 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 vivax AMA-1 (1000–0.01 copies/µL). The estimated Pearson correlation coefficient of the plasmid DNA regression curve (y = 0.0085x – 0.0495) is 0.9014 (R2 = 0.8127, P < 0.05)Back to article page
