ddGTP(10mM)

Recommended to aliquot for use to avoid repeated freeze-thaw cycles. ddGTP (2’，3’-Dideoxyguanosine 5’-triphosphate) 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. This product is a dideoxynucleotide that serves as a chain-terminating inhibitor of DNA polymerase，is a primary substrate for nucleic acid mass spectrometry kits，and can also be used for Sanger sequencing. Storage Buffer: Ultrapure water. Molecular Formula：C₁₀H₁₃N₅Na₃O₁₂P₃；Molecular Weight：557. 13
