Fig. 3From: Droplet digital polymerase chain reaction (ddPCR) for the detection of Plasmodium knowlesi and Plasmodium vivaxStandard curve of qPCR assay run with positive plasmid DNA of Plasmodium vivax AMA-1. Plasmid DNA was ten-fold diluted serially from 1000 to 0.01 copies/μL. The slope of the plasmid DNA standard curve is –3.436, equivalent to an efficiency of 95.5.7% (R2 = 0.689)Back to article page
