FAQ-1451
Why is the RT step with the QuantiFast RT Kits much shorter compared to QuantiTect RT Kits?
The combination of Omniscript and Sensiscript Reverse Transcriptases was optimized in the QuantiFast RT-PCR Kits. In addition, an optimized dNTP concentration and the limitation of amplicon size to <300 bp allow to reduce the time for the reverse transcription step to only 10 minutes.

Sensiscript RT Kit
The Sensiscript Reverse Transcriptase (RT) Kit is ideally suited for highly sensitive applications using very small amounts of RNA (less than 50 ng), such as single-cell RT-PCR and analysis of biopsies and LMD samples. Sensiscript Reverse Transcriptase allows highly efficient RT-PCR over a wide dynamic range and extremely sensitive RT-PCR with very small RNA amounts due to its high affinity for RNA. The Sensiscript RT Kit includes Sensiscript Reverse Transcriptase, dNTPs, and an optimized reaction buffer. Simply add primers for fast and easy cDNA synthesis.
QuantiTect RT-PCR Kits
QuantiTect RT-PCR Kits enable sensitive quantification of RNA targets by real-time one-step PCR using sequence-specific probes or SYBR Green I detection. The kits also allow reliable quantification of up to 5 RNA targets in a single tube by multiplex, real-time one-step RT-PCR. The combination of a hot start and a unique PCR buffer system in the ready-to-use master mix ensures highly sensitive qRT-PCR on any real-time cycler without the need for optimization. The dNTP mix includes dUTP, allowing optional treatment with UNG. For convenience, the master mixes in QuantiTect one-step RT-PCR kits can be stored at 2–8°C. Two kit formats are available for multiplex RT-PCR using sequence-specific probes: the QuantiTect Multiplex RT-PCR Kit for cyclers that require ROX dye for fluorescence normalization, and the QuantiTect Multiplex RT-PCR NoROX Kit for all other cyclers. The QuantiTect SYBR Green RT-PCR Kit is supplied with an optimized RT mix for efficient and sensitive reverse transcription over a wide range of RNA template amounts.
Omniscript RT Kit
The Omniscript Reverse Transcription (RT) Kit is specially designed for reverse transcription with any amount of RNA from 50 ng to 2 μg per reaction. A high affinity for RNA allows Omniscript Reverse Transcriptase to provide superior performance compared with other reverse transcriptases, delivering higher sensitivity in RT-PCR, even with low-copy numbers. The Omniscript RT Kit includes Omniscript Reverse Transcriptase, dNTPs and an optimized reaction buffer. Simply add primers for fast and easy cDNA synthesis.
