一般描述

DMT-2′O-TBDMS-rG(ib) Phosphoramidite belongs to the group of 2′O-TBDMS RNA Phosphoramidites.

应用

RNA interference (RNAi) has become a popular tool for the sequence-specific inhibition of gene expression and can be used in target validation and other drug development techniques. The most convenient method to provide sequence-specific RNA oligonucleotides is a chemical synthesis on a solid support with RNA phosphoramidites and RNA CPG, analogous to DNA synthesis.

特点和优势

  • 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

其他说明

The unique properties of RNA have stimulated the development of a variety of applications in diagnostics and therapeutics, as well as in basic molecular biology research where RNA can be used as:
  • Catalytic agents (ribozymes)
  • Affinity ligands (aptamers)
  • Agents to induce gene silencing (RNA interference) (a)
