Crystal Taq™ DNA Polymerase


Please Call for Pre-Orders. Currently Out of Stock.

The world’s first Taq polymerase free from background bacterial animal DNA contamination, following a breakthrough in enzyme production.

● Engineered for highly sensitive applications; qPCR and RT-PCR
● High yield and zero contamination, insuring sample longevity
● Cleaner Amplicons for Pyrosequencing
● This enzyme is from a recombinant source

100 Cycle Certification

The enzyme does not show any nonspecific endo- or exo-nuclease activities. The result of 16S assay on our Crystal Taq™ DNA polymerase showed no bacterial DNA contamination after 100 PCR cycles.


● Gene Amplification (PCR) and Sequencing
● Pyrosequencing and Sanger Sequencing
● Diagnostics*


● The lack of background bacterial and animal DNA will minimize non-specific amplification of target regions. Current levels of contamination in commercial competitor reagents reduce the quality and accuracy of whole genome sequencing. The technology behind Crystal Taq™ will greatly increase the efficiency of random genome amplification for sequencing.
● Higher sensitivity will increase overall accuracy. Crystal Taq™ will reduce the overall need for repetitive testing. Required fluorescent dye for real time PCR not included, but available for purchase.
● Crystal Taq™ will create cleaner amplicons resulting in a higher resolution sequencing result.
● Dramatically reduces false positive rates. Lack of background bacterial and animal DNA will increase the accuracy of diagnostics tests.

Detailed Description

Crystal Taq™ DNA Polymerase is from Thermus aquaticus. It is a thermostable enzyme with 5’-3’ DNA polymerase activity and 5′-3’ exonuclease activity, while lacking 3’-5’  exonuclease (proofreading) activity. The enzyme is free from bacterial and animal DNA. This first truly pure enzyme will greatly aid new generations of sequencing technologies, while being a superior component to pathogen testing in Clinical Medicine, Food-Borne contamination, Quality Assurance, Forensics, Water Treatment, Veterinary & Agriculture and Bioterrorism.
