Webthe process is amenable to automation on computer-controlled solid-phase synthesizers. Solid supports. Solid supports (also called resins) are the insoluble particles, typically 50-200 μm in diameter, to which the oligonucleotide is bound during synthesis. ... Following detritylation, the support-bound nucleoside is ready to react with the ... As mentioned above, the naturally occurring nucleotides (nucleoside-3'- or 5'-phosphates) and their phosphodiester analogs are insufficiently reactive to afford an expeditious synthetic preparation of oligonucleotides in high yields. The selectivity and the rate of the formation of internucleosidic linkages is dramatically improved by using 3'-O-(N,N-diisopropyl phosphoramidite) deriva…

WebDec 8, 2016 · The reaction of primary, secondary, allylic and benzylic trityl ethers with indium powder in MeOH/NH 4 Cl led to reductive cleavage of the trityl-oxygen bond, affording the corresponding alcohols in good to excellent yield under very mild reaction conditions. The detritylation process could successfully be extended to mono and … WebThe typical process used in synthetically creating DNA is the phosphoramidite method. This method is replicated in the 3'- to 5'- direction which is opposite to that in nature. One amidite base is added per synthesis cycle. When the sequence is completed the DNA is separated from the solid support and the base protecting groups are removed. can i play the hive on java
