The present invention provides methods, compositions, mixtures and kits utilizing 5-Chloro-2-methyl-4-isothiazolin-3-one in sequencing reactions, and in particular, sequencing reactions where deoxynucleoside triphosphates comprising a 3′-O position capped by a disulfide-based 3′-terminator group are used. In one embodiment, the deoxynucleoside triphosphates comprise a 3′-O position capped by a group comprising methylenedisulfide as a cleavable protecting group and a detectable label reversibly connected to the nucleobase of said deoxynucleoside. In addition, thiol-containing compounds and scavengers of thio-containing compounds are described. Such compounds provide new possibilities for future sequencing technologies, including but not limited to Sequencing by Synthesis.
本发明提供了利用5-氯-2-甲基-4-异噻唑啉-3-酮在测序反应中的方法、组合物、混合物和试剂盒,特别是在使用由二硫化物基团封端的3′-O位置的脱氧核苷三磷酸的测序反应中。在一种实施例中,脱氧核苷三磷酸包括由亚甲基二硫醚作为可切割保护基团的3′-O位置,并且可检测标签可逆地连接到所述脱氧核苷的核碱基。此外,描述了含硫醇化合物和硫醇化合物的清除剂。这些化合物为未来的测序技术提供了新的可能性,包括但不限于合成测序。
