Melt curve analysis
Melt curve analysis analyzes the derivative of the raw data after smoothing. This analysis is
commonly used for genotyping and allelic discrimination. Peaks in the curve are grouped into bins,
and all peaks below the threshold are discarded. Bins can then be mapped to genotypes using the
“Genotypes” command.
After a run has finished, for some chemistries a melt step can be added to visualize the dissociation
kinetics of the amplified products. The temperature is increased at a linear rate and the fluorescence
of each sample is recorded. A typical melt curve analysis is shown below.
