WebDec 8, 2024 · Although for most reagents, this is generally not an issue, extending the contact time of the detritylation reagent with oligodeoxynucleotides, which are sensitive to acid-based depurination and further strand cleavage during C&D, would lead to lower FLP (Full Length Product) purity (Fig. 5).
WebTraditionally dilute solutions of trichloroacetic acid (TCA, pK a 0.8) or dichloroacetic acid (DCA, p Ka 1.5) in dichloromethane (DCM) were used as detritylation reagent for ON synthesis. 125b, 132 Later, it was recognized that a high concentration of a weak acid (15% DCA in DCM) is more effective at driving detritylation toward completion than ... WebDetritylation using TCA is quite fast and, for this reason, it is the standard deblocking reagent on most DNA synthesizers. However, TCA is strong enough to protonate the N7 …
WebRNA deprotection is unique because of the necessity to retain the 2' protecting group during cleavage and base deprotection. 2'-OMe-RNA and 2'-F-RNA, however, are virtually identical to DNA during deprotection. But, if a hybrid oligonucleotide contains even a single RNA linkage (with the exception of a 3'-ribonucleoside linkage), the oligo must ... Webdetritylation, i.e., the removal of the DMTr group from the 5′-end of the leader nucleoside with 2% dichloroacetic acid in methylene chloride; (ii) washing, with acetonitrile to …
