5-ap-2'-dCTP is 5-(3-aminopropargyl)-2'-deoxycytidine-5'-triphosphate: a modified dCTP carrying a primary amine on a propargyl (alkyne) linker at the C5 of cytosine. Key identifiers include CAS 115899-39-3, molecular formula C12H19N4O13P3, and molecular weight 520.22 (PubChem CID 11283796).
DNA polymerases incorporate deoxynucleoside triphosphate substrates during template-directed DNA synthesis. This amine-modified dCTP places a primary amine into the DNA; that aliphatic amine then reacts specifically with amine-reactive reporters — such as NHS-ester dyes — so the DNA can be labeled after synthesis.

응용 맥락
- Amine label handle in DNA: incorporated by DNA polymerase during enzymatic DNA synthesis, placing a primary amine (on a C5 propargyl linker) into the product.
- Post-synthetic dye labeling: the amine reacts with amine-reactive reporters (e.g. NHS-ester dyes) to label the DNA.
- Cytosine analogue: installs the label at cytosine positions during enzymatic DNA synthesis.

자주 묻는 질문
What is 5-ap-2'-dCTP used for?
It is a 5-aminopropargyl-dCTP: a modified dCTP with a primary amine on a propargyl linker at cytosine. DNA polymerases incorporate it during enzymatic DNA synthesis, placing an amine in the DNA; the amine then reacts with amine-reactive dyes (e.g. NHS esters) to label the product.
Why label with an amine instead of a pre-attached dye?
A small amine linker is incorporated more efficiently by polymerases than a bulky dye. The dye is attached afterward, via the amine, giving efficient incorporation and flexible choice of reporter.
