What is DMT-dA(bz) Phosphoramidite?

General Description

DMT-dA(bz) Phosphoramidite belongs to the group of DNA Phosphoramidites. Its key features include:
Exocyclic amine functions are protected by a benzoyl group (dA(bz) anddC(bz)) or isobutyryl group (dG(ib)).
Recommended cleavage and deprotection conditions are 8 hours at 55 °Cor 24 hours at room temperature using concentrated ammonia solution,for standard base-protected oligonucleotides.
The high coupling efficiency of Proligo′s DNA phosphoramidites leads tohigh-yield and high-quality oligonucleotides.

The Uses of DMT-dA(bz) Phosphoramidite

N6-Benzoyl-2’-deoxy-5’-O-DMT-cytidine 3’-CE Phosphoramidite is used to prepare antisense oligonucleotides containing conformationally constrained methoxyaminomethylene and aminooxymethylene and aminomethylene bridged nucleoside analogs.
