License-free TopTaq Polymerase
Robust enzymes to overcome PCR inhibitors
Special enzymes for special applications
Enzymes and reagents for diagnostics
Back to topLicense-free TopTaq Polymerase

TopTaq Polymerase combines a number of convenient and unique features to provide unrivaled ease of use and ensure high DNA yields in a wide range of PCR applications. The unique TopTaq Stabilizer included in the enzyme storage buffer allows storage of TopTaq DNA Polymerase at 4°C and reaction setup at room temperature without time-consuming thawing of reagents. High yields of PCR products are achieved, even when amplifying a range of different sized fragments using the same Mg2+ concentrations and annealing temperatures.

Back to topRobust enzymes to overcome PCR inhibitors

QIAGEN Quality enzymes enable gene expression analysis and other quantitative applications especially from crude samples such as lysates, blood spots, plant tissues, and other samples containing high levels of PCR inhibitors. The hot-start enzymes are highly stable at room temperature and provide fast-cycling protocols, with high-precision amplification.

Back to topSpecial enzymes for special applications

As your OEM partner, QIAGEN can draw on decades of experience, resources, and expertise to provide enzymes optimized for a wide range of specialist applications. The range of enzymes and reagents for PCR and whole genome amplification available to you goes far beyond those available in our standard catalog. Please inquire for details.

Back to topEnzymes and reagents for diagnostics

With a deep understanding and a wealth of experience in molecular diagnostics, QIAGEN is your ideal partner when designing diagnostic assays. For diagnostic assays, QIAGEN recommends GMP Oligos from SGS. These superior quality oligonucleotides for molecular diagnostics combine with QIAGEN PCR enzymes to provide the reliability, specificity, and sensitivity needed for diagnostic assays.
