ddGTP (trisodium)

ddGTP (2′,3′-Dideoxyguanosine 5′-triphosphate) trisodium 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].
