7-ap-7-Deaza-2'-dGTP is 7-(3-aminopropargyl)-7-deaza-2'-deoxyguanosine-5'-triphosphate: a 7-deazaguanine dGTP analogue (the purine N7 is replaced by C7) carrying a primary amine on a propargyl (alkyne) linker at that C7 position. Key identifiers include CAS 587848-73-5, molecular formula C14H20N5O13P3, and molecular weight 559.26 (PubChem CID 162640848).
DNA polymerases incorporate deoxynucleoside triphosphate substrates during template-directed DNA synthesis. This amine-modified 7-deaza-dGTP places a primary amine into the DNA — presented in the major groove by the 7-deaza scaffold — and that aliphatic amine then reacts specifically with amine-reactive reporters such as NHS-ester dyes, so the DNA can be labeled after synthesis.

Application context
- Amine label handle at guanine: incorporated by DNA polymerase during enzymatic DNA synthesis, placing a primary amine (on a C7 propargyl linker) at guanine positions.
- 7-deaza scaffold: the purine N7 is replaced by C7, positioning the label in the major groove.
- Post-synthetic dye labeling: the amine reacts with amine-reactive reporters (e.g. NHS-ester dyes) to label the DNA.

Frequently Asked Questions
What is 7-ap-7-Deaza-2'-dGTP used for?
It is a 7-deaza-dGTP analogue with a primary amine on a C7 propargyl linker. DNA polymerases incorporate it during enzymatic DNA synthesis at guanine positions, placing an amine in the DNA; the amine then reacts with amine-reactive dyes (e.g. NHS esters) to label the product.
What does '7-deaza' mean?
In a 7-deaza purine, the nitrogen at position 7 of the purine ring is replaced by a carbon. This provides an attachment point (C7) for the label in the major groove and is a common scaffold for labeled purine nucleotides.
