Can I make a master mix with QuantiProbes, primers, and all other reaction components and store it for later use?
FAQ ID -584

Yes, probes and primers can be added to the QuantiTect Probe PCR- and the QuantiTect Probe RT-PCR Master Mix. This master mix can be stored at -20°C for up to 50 days, with a maximum of six freeze-thaw cycles (tested in our labs).

The master mix must be stored protected from light to avoid bleaching of the fluorescent probe. However, the QuantiTect RT Mix should be stored separately at –20°C, because the reverse transcriptases are sensitive to freezing in an aqueous environment. The QuantiTect RT Mix should be added to this master mix just prior to adding the template RNA and placing the reactions into the thermal cycler.
