General description

DMT-2′Fluoro-dU Phosphoramidite is a 2′Fluoro phosphoramidite that is used to synthesize oligonucleotides that are more thermally stable and provide increased nuclease resistance.

Its key features are-

  • Can be employed together with DNA or RNA phosphoramidites
  • Recommended deprotection conditions are 8 hours at 55 °C using concentrated ammonia solution, or with AMA for 10 minutes at 65 °C
  • Synthesis of 2′Fluoro oligonucleotides is similar to standard DNA synthesis but requires an elongated coupling time (recommended is 3 minutes compared to 90 seconds for DNA monomers)
  • Consistent lot-to-lot high purity and performance
  • Manufactured under a certified ISO 9001 quality system

Application

DMT-2′Fluoro-dU Phosphoramidite is suitable for use in the synthesis of 2′-fluoro modified oligonucleotide sequences by employing automated solid-phase chemistry.
