7-ap-7-Deaza-ddATP is 7-(3-aminopropargyl)-7-deaza-2',3'-dideoxyadenosine-5'-triphosphate: a 7-deaza (purine N7 replaced by C7) 2',3'-dideoxy ATP chain terminator carrying a primary amine on a propargyl (alkyne) linker at C7. Key identifiers include CAS 114748-69-5, molecular formula C14H20N5O11P3, and molecular weight 527.26 (PubChem CID 11249496).

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 C7 primary amine is a labelling handle for attaching a dye, presented in the major groove by the 7-deaza scaffold, so this reagent serves as a building block for labeled dye-terminators.

用途情報

  • Chain terminator: a 7-deaza 2',3'-dideoxy-ATP that stops DNA-polymerase extension when incorporated (the basis of Sanger sequencing).
  • Amine label handle in the major groove: the C7 aminopropargyl group (on the 7-deaza scaffold) lets a dye be attached, giving a labeled terminator.
  • Dye-terminator building block: used to prepare fluorescent ddNTP terminators for sequencing.

よくある質問

What is 7-ap-7-Deaza-ddATP used for?

It is a 7-deaza 2',3'-dideoxy-ATP chain terminator with a C7 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 the 7-deaza modification on a dideoxy terminator?

Replacing the purine N7 with C7 provides an attachment point in the major groove for the label and avoids a hydrogen-bonding nitrogen there. Combined with the missing 3'-OH (which terminates synthesis), it gives a well-behaved labeled purine terminator.
