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.
2X reaction buffer containing dATP, dCTP, dGTP, dTTP, magnesium chloride, reverse transcriptase, RNase inhibitor protein, hot-start DNA polymerase, ROX reference dye (if applicable), inert blue qPCR dye, and stabilizers

This product is for R&D use only, not for drug, household, or other uses. Please consult the Safety Data Sheet for information regarding hazards and safe handling practices.
KiCqStart™ One-Step Probe RT-qPCR ReadyMix™ is stable for one year when stored in a constant temperature freezer at -20 ºC protected from light. Repeated freezing and thawing does not affect RT-qPCR performance.
Different real-time PCR systems employ different strategies for the normalization of fluorescent signals and correction of well-to-well optical variations. It is critical to match the appropriate qPCR reagent to your specific instrument. Please consult the following table, or visit our PCR Selection page to find the optimal kit for your instrument platform.
Final reaction volume may vary from 10 to 50 μL, scale all components proportionally.
After sealing each reaction, vortex gently to mix contents. Centrifuge briefly to collect components at the bottom of the reaction tube.
Incubate complete reaction mix in a real-time PCR detection system as follows:
Kit components are free of contaminating DNase and RNase. KiCqStart™ One-Step Probe RT-qPCR ReadyMix™ is functionally tested in RT-qPCR. Kinetic analysis must demonstrate linear resolution over six orders of dynamic range (r2> 0.995) and a PCR efficiency > 90%.
