General description

DMT-2′O-TC-rU Phosphoramidite belongs to TC RNA Phosphoramidites. These highly regarded, innovative monomers allow faster and more efficient RNA-based oligonucleotide manufacturing and the potential to build longer RNA oligonucleotides (>100 bases). TC RNA Phosphoramidites streamline the deprotection process resulting in consistently high-quality products, offering time and cost savings.

Features and Benefits

  • Reduced coupling times
  • Improved coupling efficiency
  • Single-step downstream process with neat Ethylenediamine (EDA)
  • Cleavage and deprotection within two hours at ambient temperature
  • Desalting of oligos not required
  • Allows for manufacturing of long RNA oligomers
  • High yields of final oligonucleotides
  • Next-day RNA oligo delivery
