3'-O-allyl-2'-dTTP is 3'-O-allyl-thymidine-5'-triphosphate: a reversible-terminator dTTP whose 3'-hydroxyl is capped with an allyl (prop-2-en-1-yl) group. Key identifiers include CAS 917766-47-3, molecular formula C13H21N2O14P3, and molecular weight 522.23 (PubChem CID 77134385).
3'-O-modified nucleotides — the 3'-OH capped with a small reversible moiety — are still recognized by DNA polymerase as substrates and act as reversible terminators: incorporation adds one base and stops extension. After each incorporation and readout, the 3'-O-allyl cap is removed to regenerate the 3'-OH so the polymerase reinitiates — the basis of cyclic reversible-terminator sequencing-by-synthesis.

Contexto de aplicación
- Reversible terminator: DNA polymerase incorporates it, adding one thymine and stopping extension for that cycle.
- Cap removal reinitiates: removing the 3'-O-allyl cap regenerates the 3'-OH so synthesis continues — enabling cyclic sequencing-by-synthesis.
- Thymine building block: supplies the thymine reversible terminator in a four-nucleotide SBS set.

Preguntas frecuentes
What is a 3'-O-allyl reversible terminator?
It is a dNTP whose 3'-hydroxyl is capped with an allyl group. DNA polymerase still incorporates it, but the cap stops further extension after one base. Removing the allyl cap regenerates the 3'-OH so synthesis can continue — the principle of cyclic reversible-terminator sequencing-by-synthesis.
Which base does this terminator add?
It is the thymine (T) reversible terminator — 3'-O-allyl-thymidine-5'-triphosphate. Together with the A, C, and G 3'-O-allyl terminators it forms a four-nucleotide set for sequencing-by-synthesis.
