In the field of molecular biology, RT-qPCR (Reverse Transcription Quantitative PCR) is an indispensable tool for gene expression analysis, RNA virus detection, and assessing gene expression levels in biological samples. To ensure high accuracy, sensitivity, and reproducibility, using a high-quality master mix one step is crucial. One of the most trusted products in laboratories today is the One-Step Takyon® Ultra Probe 4X MasterMix from Eurogentec.

1. Packaging Specifications

The PCR master mix One-Step Takyon® Ultra Probe 4X MasterMix comes with the following standard specifications:

- Takyon® Ultra is avalaible in various pack-size from 200 to 10,000 - 20 µL Reactions. Larger batches and custom packaging are available on request.

- Packaging: solution form in bottles or pre-aliquoted 1.5 mL tubes, 4X concentration, available with or without reverse transcriptase enzyme and RNase inhibitor (in full kit option)

- Storage at -20°C

- A kit for 1000 reactions includes: five tubes (1 mL each; black cap) of 4X MasterMix containing Takyon® DNA polymerase, MgCl2, dNTPs, and stabilizers; two tubes (0.22 mL each; white cap) of Euroscript II RT PLUS; and one tube (0.5 mL; red cap) of ROX™ passive reference dye. A pack of 5 includes five 1000-reaction kits.

- Takyon® Ultra is an optimized RT-qPCR reagent with enhanced multi-primer detection capabilities. This One-Step RT-qPCR MasterMix based on probes allows for the sensitive and specific detection of viral RNA such as SARS-CoV-2, Influenza, and RSV, across a broad dynamic range. Combined with the improved Euroscript II Plus, this reagent enables convenient high-throughput automation setup at room temperature.

2. Applications

The master mix one step – One-Step Takyon® Ultra Probe 4X MasterMix – is widely applied in:

- Detection and quantification of RNA viruses (e.g., SARS-CoV-2, Influenza, Dengue…)

- Gene expression analysis in molecular biology research

- Biomedical, veterinary, agricultural, and food diagnostics

- Transcriptome analysis and RNA variant research

3. Principle

Master mix one step is a reaction mixture designed to perform both reverse transcription and PCR amplification in a single tube. The process includes:

- Reverse transcription: Sample RNA is converted into cDNA using reverse transcriptase enzyme

- Amplification: The cDNA is then amplified in real-time using DNA polymerase, with the help of fluorescent probes such as TaqMan®

This streamlined process minimizes contamination risk and hands-on time while ensuring high reliability in RNA detection.

4. Benefits

- 4X concentration: Allows for the addition of larger RNA sample volumes, enhancing sensitivity for low RNA concentration samples

- Complete One-Step format: Combines reverse transcriptase and DNA polymerase in one tube – saving time and reducing contamination risks

- Optimized for fluorescent probes: Compatible with various probes including TaqMan® and Molecular Beacons

- High performance and superior accuracy: Ensures excellent reproducibility across runs

- User-friendly: Easy to use, suitable for both standard and advanced qPCR platforms

- Stable and long shelf life: Withstands multiple freeze–thaw cycles, supporting convenient storage and shipping

- FAST 4X MasterMix: A more concentrated mix to maximize template volume, delivering FAST RESULTS

- Enhanced multiplexing: Enables simultaneous diagnosis of multiple pathogens in a single test

- Compatible with all thermocyclers: Includes separate ROX™ vials for optimal performance across ROX-based platforms

The One-Step Takyon® Ultra Probe 4X MasterMix is an ideal choice for RT-qPCR applications thanks to its intelligent design, outstanding performance, and high flexibility. Using a master mix one step not only improves sensitivity and accuracy but also saves time and effort in the lab. If you're seeking a comprehensive, stable, and efficient solution for RNA testing, this Eurogentec product is undoubtedly one of the top options available.
