How to interpret pcr data
The qPCR detection methods use a fluorescent signal to measure the amount of DNA in a sample. The fluorescence can be expressed as “R” (raw fluorescence) or “Rn “ (normalized reporter). The Rn value is a value calculated by dividing the fluorescence of the reporter dye (e.g., SYBR Green) by the fluorescence … Meer weergeven Figure 1.Illustrative example of a qPCR or RT-qPCR chart with the six main elements labeled.
