Is it possible to import a standard curve from a previous PCR run on the Rotor-Gene Q?

Yes. If the reaction efficiency between two PCR runs is not expected to vary, importing a standard curve from a previous run allows to estimate concentrations when a standard curve for the current run is not available. Curves can be imported from another channel, or from another run by clicking on 'Import Curve' in the Rotor-Gene Q software. Standard curves can be adjusted such that only the efficiency of the source curve is imported into the current run. Whether a standard curve should be adjusted depends on the PCR chemistry used. To adjust a standard curve, use a reference with a known concentration in the target run.
