qScript® XLT One-Step RT-qPCR ToughMix® is a ready-to-use, highly sensitive master mix for reverse transcription quantitative PCR (RT-qPCR) of RNA templates using hybridization probe detection chemistries such as TaqMan® 5′-hydrolysis probes. First-strand cDNA synthesis and subsequent PCR amplification are carried out seamlessly in the same reaction mixture with optimized 1-step thermal cycling parameters. This kit is ideal for highly sensitive quantification of RNA viruses or low abundance RNA targets as well as high throughput gene-expression studies. The system has been optimized to deliver maximum RT-PCR efficiency, sensitivity, and specificity in minimal reaction volumes and accelerated thermal cycling rates. The only necessary user-supplied materials for RT-qPCR is RNA sample and probe assay. It is compatible with all types of molecular probe assays including dual-labeling strategies. Elevating cDNA synthesis reaction temperature to 50-55°C during one-step RT-qPCR improves primer annealing and disruption of RNA secondary structure that can interfere with cDNA synthesis.
