Sensitivity of the multiplex qRT-PCR assay using DNA standards. (a) Representative amplification plot of the different concentrations of plasmids expressing the targeted H7 or N9 genes (10-fold dilutions). (b) Standard curve for ten-fold serial dilutions of the DNA standards. The log numbers of plasmids (Copies/μL) are expressed linearly on the x-axis, whereas Ct values obtained from qRT-PCR are expressed linearly on the y-axis. H7-W, H7-M, N9-W and N9-M are defined the same with Fig. 1
