|DDTT: Sulfurization agent for DNA and RNA Synthesis
DDTT is a crystalline, smelless compound that contains no oxygen atoms. The use of DDTT in the
sulfurization step of oligonucleotide synthesis results in a very high percentage of sulfurization. Our studies
showed that the content of PO linkages in mixed-base 20-mer oligodeoxynucleotide phosphorothioates
synthesized using DDTT is typically less than 2%.
In RNA synthesis, most sulfuriation agents including 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage
Reagent) are often inefficient. In contrast, the use of DDTT results in less than 10% (typically 6-8%) of the
DDTT is a proprietary agent developed and marketed by our company (US 7,723,528).
