WebNational Center for Biotechnology Information WebDetritylation is observed in less than 2 hours and most frequently in only 10 minutes. The method is advantageously used for detritylation of oligonucleotides following large scale synthesis.
WebApr 8, 2024 · Here the authors propose an RNA interference-based switch for dynamic control of AAV transgene expression. In this approach, transgene expression may be silenced by RNAi and subsequently recovered ... WebWe report here a mild detritylation strategy in mildly acidic buffers to remove the DMTr protection from the 5'-hydroxyl groups of synthetic nucleic acids. The DMTr-groups can be easily and effectively removed at pH 4.5 or 5.0 with slight warming up (40 °C), offering virtually quantitative deprotection.
