QuantiFast Multiplex RT-PCR Kits enable fast and reliable quantification of up to 4 RNA targets in a single tube by multiplex, real-time one-step RT-PCR. A special blend of reverse transcriptases delivers fast and efficient cDNA synthesis. Q-bond technology and an optimized master mix promote fast, multiplex real-time RT-PCR, 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 Multiplex RT-PCR Kit for cyclers that require ROX dye for fluorescence normalization, and the QuantiTect Multiplex RT-PCR +R Kit for all other cyclers. For convenience, the master mix can be stored at 2–8°C.
