Description

General description

DMT-dT Phosphoramidite belongs to the DNA Phosphoramidites group. Some key features of standard protected DNA phosphoramidite are mentioned below:

• 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 to high-yield and high-quality oligonucleotides
