Polymerizable dT (PdT) phosphoramidite

Using a polymerizable phosphoramidite as the coupling agent in the last synthetic cycle of automated oligodeoxynucleotide (ODN) synthesis, a polymerizable group (i.e. methacrylamide group) can be attached to the full-length ODN (but not to the failure ODNs). After cleavage and deprotection, the full-length ODN is co-polymerized into an insoluble polyacrylamide gel (the failure ODNs are not). The failure ODNs and other impurities are washed away with water. The full-length ODN is then cleaved and extracted from the gel.

  • Capable of isolation of full-length ODN from complex crude mixture
  • Useful for the synthesis and purification of long ODNs
  • Synthesis and purification of up to 400-mer has been demonstrated
  • Overcoming challenges in the synthesis of genes containing long repeats and stable higher order structures that cannot be overcome using traditional PCR assembly methods
