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

Description

qScript 1-Step Virus ToughMix is a 2x, ready-to-use, master mix for rapid detection of RNA viruses such as Flu-A, Flu-B, and SARS-CoV-2, using one-step, or single-tube reverse transcription quantitative PCR (RT-qPCR). It has been optimized for maximum sensitivity to enable reliable quantification of very low input quantities of RNA using dual-labeled hydrolysis probe detection chemistries such as TaqMan® probes in single or multiplexed assay formats. qScript 1-Step Virus ToughMix contains all required components for RT-qPCR except RNA template and primer/probe assays.

qScript 1-Step Virus ToughMix is powered by an engineered reverse transcriptase with reduced RNase H activity and improved activity and stability at higher temperatures, that includes a RT Hot-Start technology to suppresses non-specific primer extension by the RT before cDNA synthesis. The use of higher temperatures (50 to 55°C) for the first-strand step of one-step RT-qPCR provides higher specificity for primer annealing and disruption of RNA secondary structure that can interfere with cDNA synthesis. These features combined with a stringent mAb hot-start Taq polymerase and ToughMix reagent technology to neutralize many common PCR inhibitors, provide reproducible low-copy quantification as well as extended room temperature stability of fully assembled reactions for automated reaction assembly.

qScript 1-Step Virus ToughMix does not contain an internal reference dye.

E Gene Comparison: Improvement of Low Copy RT-qPCR Performance

qScript 1-Step Virus ToughMix was compared to the qScript XLT 1-Step RT-qPCR ToughMix.with the E Gene. Both mixes produced very good results with the former having slightly improved low copy RT-qPCR performance at both 150 and 15 copies of RNA.
