Figure 2From: Quantitative analysis of waterfowl parvoviruses in geese and Muscovy ducks by real-time polymerase chain reaction: correlation between age, clinical symptoms and DNA copy number of waterfowl parvovirusesStandard curve for the quantification of viral copy number by real-time PCR. The used ten-fold dilutions ranged from 1.0 × 103 to 1.0 × 106 copies per μL and were plotted as X-axis. CT values are indicated on Y-axis. Standard deviation for each dilution of pITR plasmid was marked as "whiskers". The standard curve parameters calculation were given above the curve.Back to article page
