What does an amplification plot show?
The Amplification Plot screen displays post-run amplification of the samples of each experiment added to your project. Three plots are available: ΔRn vs Cycle—ΔRn is the magnitude of normalized fluorescence signal generated by the reporter at each cycle during the PCR amplification (ΔRn = Rn – baseline).
What is linear range of PCR?
Dynamic range is the range of input template (between the highest and lowest input RNA or DNA) for which acceptable linearity (R2 is ≥0.980) and efficiency (preferably between 90 and 110%) are observed.
What is amplification plot in real-time PCR?
Amplification plots are created when the fluorescent signal from each sample is plotted against cycle number; therefore, amplification plots represent the accumulation of product over the duration of the real-time PCR experiment. The samples used to create the plots are a dilution series of the target DNA sequence.
What is linear concentration range?
Linear range or linear dynamic range – The range of concentrations where the signals are directly proportional to the concentration of the analyte in the sample.
Why is linear range important?
Understanding linear range is important for accurate detection of your target samples and the interpretation of your results.
Why is there no amplification in qPCR?
No signal or amplification can result from a number of causes ranging from problems with the assay design to inadvertently leaving out a necessary component from the reaction.
What are the phases in a qPCR amplification plot?
A standard qPCR amplification curve has three distinct phases: (1) a baseline that gradually transitions into (2) an exponential region, followed by (3) a plateau, which indicates that amplification is reducing.
What does the amplification plot Screen Show?
Amplification plot. The Amplification Plot screen displays post-run amplification of the samples of each experiment added to your project.

What are the phases of a qPCR amplification curve?
A standard qPCR amplification curve has three distinct phases: (1) a baselinethat gradually transitions into (2) an exponential region, followed by (3) a plateau,which indicates that amplification is reducing. If your amplification curve is missing one of these phases, it’s time to start troubleshooting the possible causes.
How do I control the range of active data in amplification plots?
The range of active data in the Amplification Plot is controlled through the histogram beneath the plot, which displays the well data for the experiment tabulated by an associated numerical attribute (such as Amp Score or C T /C RT without Flags).
What is the efficiency of a PCR assay with a slope?
That means for 94% efficiency on a 5-log range, the assay would have a range of 88% to 100% efficiency. To accurately determine the efficiency of a PCR reaction, a 5-log dilution series must be performed. A slope of –3.3 ±10% reflects an efficiency of 100% ±10%.
