Sahara Universal qPCR Master Mix

Sahara Universal qPCR Master Mix



  • Multiplex two Real-Time PCR reactions with no effect on Cq’s
  • Extreme thermal stability: withstands three months at 25 ºC with no impact on efficiency
  • Overcomes inhibition in crude extracts and environmental samples
  • Universal mix runs fast protocols, amplifies GC-rich targets, and incorporates aptamer-based hot start and dUTP carry-over prevention systems
  • License-free for commercial or diagnostic use


Sahara Universal qPCR Master Mix is a 2X Taq mix for probe-based Real-Time PCR. It quantitatively amplifies qPCR targets at high efficiency from purified samples and crude extracts.

The Most Stable Master Mix on the Planet

Stable at 50 ºC for eight days, or 25 ºC for three months, Sahara mixes ship economically at ambient temperatures, prevent Cq drift over time due to thermal degradation, and are ideal for high throughput or field applications where temperature control is not always ideal.

Amplifies Everything Without Inhibition

Sahara Universal qPCR Master Mix has been validated against genomic, plasmid, and cDNA targets from a wide range of organisms. The mix supports both standard and fast protocols, and amplifies GC-rich targets up to 70%.

Numerous enhancers bind & inactivate PCR inhibitors, allowing amplification from crude extracts of:

  • Blood
  • Food & beverages
  • Plant & animal tissue
  • Environmental air & water samples
Simplify your PCR

Set up reactions with ease at room temperature: an aptamer-based hotstart system prevents amplification from occurring below 50 ºC, while a blue non-interfering loading dye helps avoid pipetting errors. When activated by the addition of UNG, a dUTP carry-over prevention system prevents false positives from amplicon contamination.

  • What is a PCR Master Mix?
    A PCR master mix is a premixed solution that contains most of the components necessary to run a PCR assay. The mix contains Taq DNA polymerase, dNTPs, MgCl2, as well as enhancers and stabilizers in a buffer that is optimized for DNA amplification by PCR. Read more...
