Preparing a LightCycler® 480 System Gene Scanning Experiment
PCR Parameters
PCR Parameters5
Data obtained from High Resolution Melting is only as good as the amplification product
being analyzed. Nothing is more critical to High Resolution Melting data than having ro-
bust amplification of a single product. The High Resolution Melting Dye binds all double-
stranded DNA present in a reaction. Specific amplification product, undesired amplifica-
tion product(s), and primer-dimer products all bind the dye with equal affinity; thus all
contribute to the overall fluorescence and melting profile.
To optimize the amplification, determine the best thermal cycling parameters. If you use
the LightCycler® 480 High Resolution Master to establish your LightCycler® 480 Gene
Scanning assay, you can use the following parameters in your initial experiments:
