General description

KiCqStart® One-Step Probe RT-qPCR ReadyMix 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 on real-time PCR systems (refer to instrument compatibility section to select the appropriate reagent for your machine). First-strand cDNA synthesis and PCR amplification are carried out in the same tube without opening between procedures. It 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 reduced reaction volumes and fast cycle times.

KiCqStart® One-Step Probe RT-qPCR ReadyMix contains all required components for RT-qPCR except RNA template and probe. It is compatible with all dual-labeled probe chemistries. The reverse transcriptase is an engineered M-MLV with reduced RNase H activity and improved activity and stability at higher temperatures. 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.

KiCqStart® One-Step Probe RT-qPCR ReadyMix is highly resistant to PCR inhibitors. A key component of the ReadyMix is an ultra-pure, highly processive, thermostable DNA polymerase that is combined with high avidity monoclonal antibodies. This provides an extremely stringent automatic hot-start that minimizes the potential for primer-dimer and other non-specific PCR artifacts. The light blue color of the inert dye simplifies reaction assembly in white, or clear, plates and helps to minimize pipetting or mixing errors. The dye does not interfere with qPCR performance or affect the stability of the product.


KiCqStart® One-Step Probe RT-qPCR ReadyMix has been used in quantitative real-time polymerase chain reaction (qRT-PCR) for gene expression studies. It has also been used in cell type-specific transcript analysis for determining the cycle threshold (Ct) value.
