Figure 1.
Linearity of both extraction methods in conjunction with Real-time RT-PCR assay.
A 10-fold dilution series of influenza virus stock (105.7 TCID50)/ml were extracted in triplicate for each dilution with the Maxwell 16-S and QIAamp Kit and then tested by the CDC Flu A Real-time RT-PCR assay. The virus concentration (log10TCID50/ml) was plotted against the mean Ct values of triplicate determinations for each dilution producing repeated positive results.
