Product information "2',3'- Dideoxyguanosine-5'-O-triphosphate (ddGTP)"
2',3'-Dideoxyguanosine-5'-O-triphosphate (ddGTP) sodium salt of purity >95% HPLC. For other salt forms or a guaranteed higher purity please inquire.
2',3'-Dideoxyguanosine-5'-triphosphate (ddGTP) is a modified nucleoside triphosphate, where the 2' and 3' hydroxyl groups are absent, resulting in chain termination. The inability of polymerases to extend from a dideoxy nucleotide causes the chain termination while PCR and is widely useful in antiviral research and in a variety of biotechnology applications. ddGTP is used in cycle sequencing, enzyme mechanistic studies and for producing RNA and DNA sequences that cannot be extended by polymerases or joined by DNA ligases.
Another notable application that utilizes a primer terminated on the 3′ end with a dideoxy modification is pyrophosphorolysis-activated polymerization (PAP). This technique is valuable for the detection of rare mutations.

ddGTP is an analogue of guanosine triphosphate (GTP) where both ribose hydroxy groups have been removed and replaced by hydrogen.
