Fig. 1From: Development of a duplex real-time PCR method for the detection of influenza C and D virusesPreparation of plasmid standards. a, b Amplification curves of ICV and IDV for each plasmid standard at concentrations ranging from 1 × 107 copies/μL to 1 × 101 copies/μL; c, d standard curves of plasmid standards of ICV and IDV. All standard curves were generated using GraphPad Prism 6 softwareBack to article page
