Fig. 3From: Real-time PCR using atpE, conventional PCR targeting different regions of difference, and flow cytometry for confirmation of Mycobacterium bovis in buffaloes and cattle from the Delta area of EgyptAmplification curve of real-time PCR assay using atpE primer/probe. The fluorescence increase wasn’t detectable until cycle 20 as enough amplified product was accumulated to yield a detectable fluorescence signal using control DNA with concentrations of (100,000, 1000, 100, 10, 1, 0.1, and 0.01 ng/μL). The crossing points and concentrations were automatically calculated by the real-time PCR software (LightCycler 480 Roche)Back to article page
