Designed for the most sensitive applications such as qPCR and RT-PCR, as well as making cleaner amplicons for Pyrosequencing, our first master mix is built to simplify gene amplification.


  1. Engineered for highly sensitive applications; qPCR and RT-PCR.
  2. High yield and zero contamination, insuring sample longevity
  3. Cleaner Amplicons for Pyrosequencing.


SKU: N/A Category:


Pharmozyme’s Crystal Taq DNA polymerase is derived 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 of animal & bacterial DNA contamination – eliminating interfering background.


  • Gene amplification (PCR) & sequencing – Avoiding bacterial DNA contamination minimizes non-specific amplification of target regions. Current contamination levels in supplier products reduce the quality and accuracy of whole genome sequencing. The technology engineered into Crystal Taq greatly increases the efficiency of random genome amplification for sequencing.
  • RT-PCR – Resulting higher sensitivity, increases overall accuracy. Crystal Taq impact reduces repeat testing, saving time & money.
    Pyrosequencing & Sanger sequencing – Crystal Taq creates cleaner amplicons resulting in higher resolution sequencing result.
  • Clinical Diagnostics, Food Pathogen Testing, Forensics, Quality Assurance Testing, Veterinary, Agriculture, Water Treatment and Bioterrorism – Elimination of False positive results caused by DNA contamination provides superior accuracy – saving lives and $Billions of dollars in those industries.

DNA templates should preferably be pure. Chemical agents, ionic detergents (such as SDS) and other DNA damaging agents should be avoided. For routine applications, 25 to 35 PCR cycles is usually enough to provide sufficient copies of the target sequence.
