General description

RNA phosphoramidites, along with RNA CPG, and analogous to DNA synthesis support the synthesis of sequence-specific RNA oligonucleotides for RNA interference (RNAi) and can be used in target validation and other drug development techniques. Modern phosphoramidite-mediated synthesis has enabled routine high-yielding preparations of RNA oligonucleotides. High-quality RNA phosphoramidites are key to low failure rates, the high biological activity of synthesis products, and cost-effectiveness.

Key Features

  • Industry-standard 2′O-TBDMS protective group
  • Consistent lot-to-lot purity and performance
  • Compatible with deprotection methods based on methylamine or AMA
  • Standard RNA phosphoramidites provide excellent coupling results when used with ETT or BTT as an activator; best results are obtained with activator 42
  • Capping with standard acetic anhydride capping reagent rather than with fast Deprotection Cap A
  • Manufactured under a certified ISO 9001 quality system
DMT-2′O-TBDMS-rA(bz) Phosphoramidite is configured for ÄKTA and OligoPilot Synthesizers.
