3'-O-cyanoethenyl-dTTP is a 3'-O-cyanoethenyl modified dTTP reversible terminator. The 3'-hydroxyl is capped with a reversible blocking group so that polymerase extension stops after a single incorporation cycle. Key identifiers for this catalog entry are CHEMOS CH66035 and CAS 2142998-82-9.
3'-O-modified nucleotides are used in cyclic reversible-terminator sequencing-by-synthesis workflows: DNA polymerase incorporates the nucleotide, extension pauses after one base, and cap removal regenerates the 3'-OH so synthesis can continue. This page keeps the identity boundary to the supplier catalog name, CAS number, and literature-supported reversible-terminator nucleotide context.

Frequently Asked Questions
What is 3'-O-cyanoethenyl-dTTP?
3'-O-cyanoethenyl-dTTP is a 3'-O-cyanoethenyl modified dTTP used as a reversible-terminator nucleotide in sequencing-by-synthesis research workflows.
How does a reversible terminator work?
DNA polymerase incorporates the nucleotide, the 3'-O blocking group pauses further extension, and removal of the cap regenerates the 3'-OH so synthesis can continue.
