report the construction of a novel chemically cleavable fluorescentlabeling system based on an allyl group to modify nucleotide for DNA sequencing by synthesis (SBS). We have found that an allyl moiety can be used successfully as a linker to tether a fluorophore to a 3'-O-allyl-modified nucleotide, forming a chemically cleavable reversibleterminator, 3'-O-allyl-dGTP-allyl-Bodipy-FL-510, for application
我们报告了一种基于烯丙基的新型化学可裂解荧光标记系统的构建,以修饰核苷酸用于合成 DNA 测序 (SBS)。我们发现烯丙基部分可以成功地用作将荧光团连接到 3'-O-烯丙基修饰的核苷酸上的接头,形成化学可切割的可逆终止子,3'-O-烯丙基-dGTP-烯丙基-Bodipy- FL-510,适用于 SBS。通过掺入 3'-O-烯丙基-dGTP-烯丙基-Bodipy-FL-510 产生的 DNA 延伸产物上的荧光团和 3'-烯丙基基团在 30 秒内通过 Pd 催化的水性脱烯基化作用同时去除。缓冲溶液。所得 DNA 产物成功用作聚合酶反应中进一步延伸的引物。
