5-ap-ddCTP is 5-(3-aminopropargyl)-2',3'-dideoxycytidine-5'-triphosphate: a 2',3'-dideoxy CTP (a chain terminator) carrying a primary amine on a propargyl (alkyne) linker at the C5 of cytosine. Key identifiers include CAS 114748-56-0, molecular formula C12H19N4O12P3, and molecular weight 504.22 (PubChem CID 21779042).
2',3'-dideoxynucleoside triphosphates act as specific chain-terminating inhibitors of DNA polymerase — the basis of Sanger dideoxy sequencing: once one is incorporated, the missing 3'-OH stops further extension. The C5 primary amine is a labelling handle for attaching a dye, so this reagent serves as a building block for labeled dye-terminators.

常见问题
What is 5-ap-ddCTP used for?
It is a 2',3'-dideoxy-CTP chain terminator with a C5 aminopropargyl amine handle. As a dideoxy nucleotide it stops DNA-polymerase extension (the basis of Sanger sequencing); the amine allows a dye to be attached, making it a building block for labeled dye-terminators.
Why does the dideoxy nucleotide terminate synthesis?
A 2',3'-dideoxynucleotide lacks the 3'-hydroxyl needed to form the next internucleotide bond. Once a polymerase incorporates it, extension stops — the principle behind dideoxy (Sanger) sequencing.
