General description

Proligo′s DNA phosphoramidites lead to high-yield and high-quality oligonucleotides due to their high coupling efficiency. The deprotection step of automated oligonucleotide synthesis is integral to synthesis time and final product quality. Exocyclic amine functions are protected by a benzoyl group (dA(bz) and dC(bz)) or isobutyryl group (dG(ib))Key features of DNA phosphoramidites :
  • 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
The product belongs to ABI™ synthesizers.
