ddGTP trisodium (100 mM in water)  (Synonyms: 2′,3′-Dideoxyguanosine 5′-triphosphate trisodium)

ddGTP (2′,3′-Dideoxyguanosine 5′-triphosphate) trisodium (100 mM in water) is one of 2',3'-dideoxyribonucleoside 5'-triphosphates (ddNTPs) that acts as chain-elongating inhibitor of DNA polymerase for DNA sequencing. ddGTP trisodium acts as an inhibitor or a substrate for DNA polymerase α^[1][2][3].

ddGTP trisodium inhibits the formation of both negative and positive DNA strands^[1].
ddGTP trisodium inhibits DNA polymerase α activity in the presence of Mn²⁺ at low concentrations (<1 μM)^[2].
ddGTP trisodium competitively inhibits the incorporation of [3H]dGTP into the DNA^[2].
