Method for synthesis of nucleoside triphosphates

10000 member PNA (peptide nucleic acid) encoded microarray

This more efficient and lower cost method for synthesis of triphosphates, using a polymer-supported reagent, generates far greater yields and higher purity material by eliminating many of the processing stages of other systems.

The importance of triphosphates and their analogues in DNA sequencing, PCR and enzyme and inhibition studies has led to various approaches for their synthesis. Yet existing methodologies do not generate triphosphates that are suitable for use in a wide range of downstream reactions or for use in library synthesis. Additionally, current methodologies involve many stages (purification, filtration etc) and are low yielding or unreliable – particularly for more complex modified or labelled nucleosides.

To overcome these limitations, researchers at the University of Edinburgh have developed a new production technique using a supported phosphorylation reagent for the synthesis of nucleoside triphosphates. This new process provides high yields, produces clean product and reduces the need for complex purification processes.

Significantly, this methodology has been proven to efficiently produce complex modified nucleosides. This technology can be used efficiently and cheaply produce a range of triphosphate compounds including modified and (fluorogenically) labelled nucleosides.
