TIPS-5-Ethynyl-dU-CE Phosphoramidite
TIPS-5-Ethynyl-dU-CE Phosphoramidite5"-Dimethoxytrityl-5-triisopropylsilyl-ethynyl-2"-deoxyUridine, 3"-[(2-cyanoethyl)-(N,N-diisopropyl)]-phosphoramidite

5-Ethynyl-dU offers convenient click conjugation with an azide to generate a label rigidly attached to one of the oligonucleotide bases. 5-Ethynyl-dU is subject to base-catalyzed hydration during cleavage and deprotection, especially when using a strong base or heat. Hydration of an ethynyl group forms a methyl ketone which subsequently blocks potential click reactions. Mild deprotection conditions are necessary when using 5-Ethynyl-dU-CE Phosphoramidite to prevent this side reaction. TIPS-5-Ethynyl-dU-CE Phosphoramidite, containing a protected alkyne, offers broader compatibility with oligonucleotide synthesis and deprotection. Protecting the 5-ethynyl group with a triisopropylsilyl (TIPS) protecting group prevents acid or base catalyzed hydration during oligonucleotide synthesis and workup. A quick treatment with TBAF removes the TIPS protecting group.
Diluent: Anhydrous Acetonitrile
Coupling: 3 minute coupling time recommended
Deprotection: No changes needed from standard method recommended by synthesizer manufacturer. TIPS removal: After deprotection, dry down oligo and take up in 0.5 mL DMF. Add 0.1 mL TBAF. Vortex and keep at 45°C for 15 minutes. Quench with 0.5 mL 2 M TEAA and desalt on Glen Gel-Pak™ column or equivalent.
Storage: Storage: Refrigerated storage, maximum of 2-8°C, dry
Stability in Solution: 1-2 Days
