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. |
