qScript XLT One-Step RT-qPCR ToughMix

Tough-tested 1-step real time PCR

Features & Benefits

• Tough Tested – Overcomes common inhibitors including polysaccharides, heme/hemoglobin, humic acid, melanin
• Flexible – Use fast or standard qPCR cycling conditions
• Broad dynamic range- Reliable data from your precious samples every time
• Multiplexing enabled – Supports highly sensitive detection for up to four targets

qScript XLT 1-Step RT-qPCR ToughMix is intended for molecular biology applications. This product is not intended for the diagnosis, prevention or treatment of a disease.

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.
