High Performance Nucleotides from Jena Bioscience

Jena Bioscience is one of only a few primary manufacturers of dNTPs for PCR. Our high quality starts with our production technology. Many problematic impurities, such as pyrophosphate and modified nucleotides, are by-products from chemical synthesis. These impurities can severely impact PCR performance. That’s why we synthesise all our dNTPs enzymatically, meaning many common impurities are never even present in our solutions. Any remaining impurities are removed with several state-of-theart purification procedures. For dATP, dCTP, dGTP, and dUTP, we start with the respective
ribonucleotide, and use the highly specific Ribonucleotide Reductase enzyme (Scheme 1). While for dTTP, we use enzymes to sequentially phosphorylate thymidine.


Scheme 1. The bacterial enzyme ribonucleotide reductase selectively reduces the 2’-OH-group of the selected ribonucleotide (NTP) to give the corresponding Deoxyribonucleotide (dNTP). Our enzymatic synthesis is performed in this manner on a kilogram scale.
