DBCO-dT Phosphoramidite
DBCO-dT Phosphoramidite is a coupling agent. DBCO-dT Phosphoramidite serves as a nucleoside-based phosphoramidite building block with a dibenzocyclooctyne (DBCO) functionality. DBCO-dT Phosphoramidite undergoes covalent coupling with azide-labeled biomolecules via metal-free click chemistry. DBCO-dT Phosphoramidite enables the introduction of click chemistry reactive groups into flexible nanoarray linkers and internal sites of oligonucleotide chains during solid-phase synthesis.

Biological Activity
DBCO-dT Phosphoramidite enables site-specific, metal-free click chemistry conjugation of two azide-labeled Aβ(14-23) peptides to a homogeneous, flexible FNA tether during automated oligonucleotide synthesis[1].
DBCO-dT Phosphoramidite-modified FNA tethers enable stable immobilization of Aβ(14-23) peptides that spontaneously form antiparallel dimers, which exhibit a most probable rupture force of 53 pN as measured by AFM force spectroscopy[1].
DBCO-dT Phosphoramidite (0.1-100 mM; 24 h)-modified oligonucleotides on polystyrene supports achieve high (94-97%) conjugation yields at internal positions near the 3′-end across all tested labels, while hydrophilic CPG supports drastically reduce yields for lipophilic labels at these positions; a 1 mM modifier concentration is sufficient for efficient conjugation across most conditions[2].
DBCO-dT Phosphoramidite (0.1-100 mM; 24 h)-modified oligonucleotides achieve ≥90% conjugation yields at the 5′-end across all tested solid supports and concentrations (0.1-100 mM) for AzaPc, ACR, and Cy5, with BDP requiring 1 mM; reaction times for maximal yields range from 30 min to 6 h depending on label polarity, and unreacted BDP can be recycled for three consecutive conjugation cycles without structural degradation and with consistently high yields[2].
