"WebFluorescence typically doubles with each additional cycle in the exponential phase of an efficient qPCR reaction; a lower slope would indicate that fluorescence is not doubling and suggest that PCR inhibitors may be present in your reaction (Fig 2, curve d). Compare this to an amplification curve of a reaction with a low copy number. " - Pcr doubling
