1. What is a master mix

- In molecular biology, a master mix is a blend of the essential components required for a PCR (Polymerase Chain Reaction) or RT-qPCR (Reverse Transcriptio What is a master mix? It is a pre-formulated recipe comprising DNA polymerase, buffer, dNTPs, MgCl₂ and sometimes stabilizers or tracking dyes

- Using a master mix saves time and ensures high accuracy and reproducibility in PCR experiments. Especially when

2. Eurogentec Master Mix – an optimal solution for PCR and RT-qPCR

Eurogentec – one of the most reputable European brands in molecular biology – has developed several lines of high-quality master mix products, suited to many research and diagnostic purposes. Notable products include:

- Takyon® No ROX Probe 2X MasterMix UNG

- Takyon® One-Step RT-qPCR MasterMix 4X Probe

- Takyon® SYBR® MasterMix

* Key features of Eurogentec master mixes

- High sensitivity: accurately detects low-copy-number targets.

- High accuracy and reproducibility: thanks to stable components optimized per application.

- Time-saving: fewer sample-preparation steps and a lower cross-contamination risk.

- UNG integration: removes carryover DNA from previous PCR reactions, increasing result reliability (for the UNG-containing lines).

- ROX-free: or in a version compatible with real-time PCR instruments that require a ROX reference standard.

* Applications of Eurogentec Master Mix

The Eurogentec master mix lines are widely used in:

- Gene expression profiling

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

- Food, environment and pharmaceutical testing

- Medical diagnostics and genetic testing

- Functional genomics and genome biology research.

3. How a master mix works

The principle of a master mix is based on the DNA chain-amplification reaction. The main master mix components are:

- DNA polymerase: the enzyme responsible for copying the target DNA.

- dNTPs (deoxynucleotide triphosphates): the building blocks for synthesizing new DNA.

- MgCl₂: the magnesium ion needed for the enzyme to work effectively.

- Buffer: maintains the pH and ideal conditions for the reaction.

- Additives: boost stability and performance (stabilizers, reaction enhancers…).

For the One-Step RT-qPCR master mix lines, the mixture also contains reverse transcriptase to convert RNA into cDNA before PCR is performed.

4. Specific usage instructions

4.1. For the Takyon® No ROX Probe 2X MasterMix UNG product

Step 1. Prepare the reaction mix:

- 10 µL of 2X Master Mix

- 0.4 µM forward primer + 0.4 µM reverse primer

- 0.2 µM probe (if used)

- Template DNA

- DNAse/RNAse-free water to a final volume of 20 µL

Step 2. Typical PCR cycling:

- 50°C, 2 minutes (if UNG is present)

- 95°C, 3 minutes

- 40 cycles: 95°C – 15 s, 60°C – 60 s

4.2. For the One-Step RT-qPCR Master Mix 4X Probe

Step 1. Add the RT enzyme from a separate vial (for the split format).

Step 2. Follow the protocol:

- 48–50°C, 10–15 minutes (reverse transcription)

- 95°C, 3 minutes (polymerase activation)

- 40 cycles: 95°C – 10 s, 60°C – 40 s
