The present disclosure provides methods of sequencing polynucleotides and compounds, compositions useful for sequencing of polynucleotides. The chemical compounds include nucleotides and their analogs which possess a sugar moiety comprising a cleavable chemical group capping the 3'-OH group and a base that is attached to a detectable label through a cleavable linker comprising a disulfide bond. In addition, the disulfide bond(s) can be cleavable by a reducing reagent. In addition, after the disulfide bond(s) is/are cleaved by the reducing reagent, there is no free thiol group linked to the nucleotides. Examples of chemical compounds according to the present disclosure are shown as Formulae (IV) and (V).
本公开提供了测序多核苷酸的方法以及用于测序多核苷酸的化合物和组合物。这些化学化合物包括核苷酸及其类似物,其具有糖基团,包括覆盖3'-OH基团的可裂解化学基团和与可裂解连接剂通过二硫键连接的可检测标签的碱基。此外,二硫键可以被还原试剂裂解。在二硫键被还原试剂裂解后,没有自由巯基与核苷酸连接。根据本公开的化学化合物的示例如公式(IV)和(V)。
