O 6-甲基-2'-脱氧鸟苷 (O6-Me-dG) 是 DNA 中的一种诱变核苷酸。使用掺有 6-S-功能化硫鸟苷的 ODN,通过功能转移反应快速、选择性地修饰 DNA 中的 O6-Me-dG。随后通过点击化学用荧光 FAM 或生物素基团标记 O6-Me-dG,从而可以灵敏且选择性地检测 DNA 中的 O6-Me-dG。
O 6-Methyl-2′-deoxyguanosine (O6-Me-dG) is a mutagenic nucleotide in DNA. O6-Me-dG in DNA was rapidly and selectively modified by a functionality transfer reaction using the ODN incorporating 6-S-functionalized thioguanosine. Subsequent labelling of O6-Me-dG with the fluorescent FAM or biotin group via click chemistry has permitted the sensitive and selective detection of O6-Me-dG in DNA.
