We define these periods (when the flow within the flowcell is stationary) as the dwell time. Finally, the reagents are drained from the bottom port (drain time), followed by washes using two flowcell volumes of acetonitrile (ACN).

Honeywell Burdick & Jackson™ Detritylation Reagent, Toluene with 10% … 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 ...
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). WebEven after long reaction times, excess of the reagent, and elevated temperatures, alkylation of the positions 2 and 3 was less than 11%, as confirmed by 13 C NMR spectroscopy (Figure 91). This selectivity is in the same range as for the unsubstituted trityl function. Moreover, the detritylation succeeds 20 times faster.
