Description

Description générale

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

Application

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.

Caractéristiques et avantages

• 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

Autres remarques

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)
