FAQ-1702
Are there problems with the default threshold setting on the Applied Biosystems 7500 when using QuantiFast Probe PCR Kits?
No. We recommend using QuantiFast Probe +ROX Vial Kits: the master mix does not contain ROX dye, but the kit is supplied with a separate tube of ROX dye. The kits allow to adjust the ROX concentration in the master mix according to your cycler’s requirements.
Please follow specific recommendations in the QuantiFast Probe PCR Handbook.

QuantiFast Probe PCR Kits
QuantiFast Probe PCR Kits deliver fast and sensitive quantification of gDNA and cDNA targets by real-time PCR and two-step RT-PCR using sequence-specific probes. Q-bond technology and an optimized master mix enable shorter real-time PCR run times, not only on fast cyclers with short ramping times, but also on standard cyclers. The combination of a hot start and a unique PCR buffer system in the ready-to-use master mix ensures highly sensitive qPCR on any real-time cycler without the need for optimization. Two kit formats are available: the QuantiFast Probe PCR Kit for cyclers that require ROX dye for fluorescence normalization, and the QuantiFast Probe PCR +ROX Vial Kit for all other cyclers. For convenience, the master mix can be stored at 2–8°C.
IMPORTANT NOTE: As announced earlier, the production of the QuantiFast kits has been discontinued since mid-2021. Hence, these products will be available only until stocks last. Visit the product page of the successor kit to view improved features or to request a trial kit.
