SYBR/Dye-Based

What is a SYBR Green Dye-Based Master Mix?

A SYBR Green dye-based master mix is a 2x, ready-to-use formulation designed for dye-based, quantitative amplification of DNA targets, including cDNA and genomic DNA, by real-time PCR. SYBR Green dye binds to double-stranded DNA formed during amplification, and the resulting fluorescence increases proportionally to the quantity of double-stranded product, providing a real-time readout of amplification progress. Choose a SYBR Green dye-based master mix for cost-effective, flexible quantification across any primer pair and target combination, especially when running many different assays without the overhead of probe design.

What you will find:

• SYBR Green dye-based qPCR master mixes for real-time quantification of DNA and cDNA targets across a wide range of research applications.
• Fast qPCR formulations with HiROX and LoROX options to support compatibility with different real-time PCR instrument platforms.
• Blue tracking dye master mixes, including AzuraView™ GreenFast and Accuris qMAX Green formats, for improved reaction setup visibility.
• One-step SYBR Green RT-qPCR mixes that combine reverse transcription and real-time PCR in a single tube for RNA quantification workflows.
• Ready-to-use 2x master mixes formulated for reproducible qPCR setup while reducing pipetting steps and workflow complexity.

How to Choose a SYBR Green Dye-Based Master Mix

Dynamic Range and Sensitivity
Look for master mixes offering a wide linear dynamic range -- some formulations provide precise measurement across approximately six logs of dynamic range, enabling accurate detection across both low- and high-concentration samples in the same assay design.

Primer Melting Temperature Flexibility
SYBR Green master mixes are commonly formulated to provide flexibility for primers with melting temperatures (Tm) in the range of approximately 55-65 °C, reducing the need for extensive primer-specific optimisation when bringing new assays online.

Bench-Top Stability
Dual hot-start mechanisms in some SYBR Green master mixes provide extended bench-top stability -- up to 72 hours at room temperature in the dark in some formulations -- with single melt curves confirmed at both initial and post-incubation time points, supporting automated and batched workflows.

Carryover Contamination Prevention
Formulations that include uracil-DNA glycosylase (UDG) and dUTP help ensure leftover DNA residue from previous reactions is not re-amplified in subsequent experiments, a useful feature for high-throughput repeat assays.

Instrument and Workflow Compatibility
Broad instrument compatibility - including standard and fast cycling modes -- and compatibility with a variety of reverse transcriptase enzymes (for RT-qPCR workflows using a separately generated cDNA) widen the range of platforms a single master mix can support.

Specifications Context

SYBR Green dye is a fluorescent double-stranded DNA-binding dye that tracks amplification progress in real-time PCR: as the reaction proceeds, the dye binds newly synthesised dsDNA at each extension step, and the resulting fluorescence increase is proportional to product quantity. Because SYBR Green is not PCR-inhibitory and works with any primer-template combination, it provides accurate, reproducible results with high sensitivity across a broad dynamic range and gives consistent results across different real-time PCR platforms - one reason dye-based chemistry remains cost-effective compared to probe-based systems, which require a different labelled probe for each target sequence. SYBR Green master mixes are typically stored at −20 °C to −30 °C and protected from light; lot-specific CoAs are available on request.
