"We can confirm that based on our testing using TEM-PCR Urinary Track and Infectious Disease panels, no false-positive results for E. coli were detected with Pharmozyme [Crystal] Taq™ DNA Polymerase." -Elena Grigorenko, PhD. VP of Research and Development at Diatherix-Eurofins

"Crystal Taq™ works well in our system, and when using an assay which amplifies all bacterial DNA reduces background by about 75% (suggesting that most background comes from the Taq, but there is still a proportion from other sources)" -Lee Smith, Head of Research, Pharmozyme's Undisclosed Int'l Diagnostics Customer

FAQ

How is Crystal Taq™ free from animal and bacterial DNA contamination?

Unlike other DNA Taq Polymerases, Crystal Taq™ is manufactured in a proprietary system that does not feature bacterial hosts and includes novel purification methods that achieve unprecedented results.

How much Crystal Taq™ DNA Polymerase is used in a PCR amplification?

Most PCR amplifications use 2.5 – 5 units of Crystal Taq DNA polymerase per 50μL reaction. A 25μL reaction would use about 1.25 – 2.5 units. However, the optimal unit concentration per reaction should be empirically determined, and often the “less is better” rule applies.

How is Crystal Taq™'s contamination-free claim tested?

The result of 16S assay on our Crystal Taq™ DNA polymerase showed no bacterial DNA contamination after 100 PCR cycles.
