DreamTaq DNA Polymerase
The Thermo Scientific™ DreamTaq™ DNA Polymerase is an enhanced Taq DNA polymerase optimized for all standard PCR applications. It ensures higher sensitivity, longer PCR products and higher yields compared to conventional Taq DNA polymerases. It is supplied with specially optimized Thermo Scientific DreamTaq buffer or Thermo Scientific DreamTaq Green buffer of proprietary formulation which enables robust DNA amplification with minimal optimization of reaction conditions.
- Robust amplification without MgCl2 optimization
- High yields of PCR products
- High sensitivity and amplicon length
- Direct loading of PCR products on gels

Ready-to-load PCR products
The DreamTaq Green format is a combination of DreamTaq DNA Polymerase and the Green Reaction Buffer. The buffer includes a density reagent and two tracking dyes for direct loading of PCR products on gels. The Green Buffer does not interfere with the performance of DreamTaq DNA Polymerase and is compatible with downstream applications including DNA sequencing, ligation and restriction digestion.

Increased PCR sensitivity and amplicon yields
DreamTaq DNA Polymerase provides higher PCR sensitivity in comparison to conventional Taq enzymes. Robust amplification can be achieved even with very low amounts of template DNA.
Figure 3: Superior yields with low amounts of DNA template. A 545 bp fragment from the human α-L-Fucosidase gene was amplified with DreamTaq DNA Polymerase and Taq DNA Polymerases from other vendors according to manufacturers’ recommendations using decreasing amounts of template DNA.

Robust amplification of longer amplicons
DreamTaq DNA Polymerase outperforms conventional Taq enzymes, providing higher yields and amplifying longer amplicons. With DreamTaq DNA polymerase it is possible to amplify targets up to 6 kb from genomic DNA and up to 20 kb from viral DNA.
Figure 4. Amplification of longer amplicons with DreamTaq DNA Polymerase. DNA fragments of increasing length were amplified with DreamTaq DNA Polymerase and Taq DNA polymerase from other vendors according to manufacturers’ recommendations. Only DreamTaq DNA Polymerase was able to amplify the longest (5000 bp) fragment. DNA Ladder: Thermo Scientific™ GeneRuler™ Express DNA Ladder.
