title: Analogs of guanine nucleoside triphosphates for sequencing applications.
abstract: We have synthesized more than 30 different deoxyribonucleosides and triphosphates with modifications either in the base or the phosphate moiety as analogs of 2'-dGTP for DNA sequencing applications. All the modified nucleoside triphosphates were tested as substrates for DNA polymerases, including Sequenase T7 DNA polymerase or Thermo Sequenase DNA polymerase. Two of the analogs, 7-ethyl-7-deaza-dGTP and 7-hydroxymethyl-7-deaza-dGTP meet our requirements as better sequencing reagents.
