The invention provides a nucleotide or nucleoside having a base attached to a detectable label via a cleavable linker, characterised in that the cleavable linker contains a moiety selected from the group comprising: Formula (I)
(wherein X is selected from the group comprising O, S, NH and NQ wherein Q is a C
1-10
substituted or unsubstituted alkyl group, Y is selected from the group comprising O, S, NH and N(allyl). T is hydrogen or a C
1-10
substituted or unsubstituted alkyl group and * indicates where the moiety is connected to the remainder of the nucleotide or nucleoside).
本发明提供了一种核苷酸或核苷,其具有通过可断链连接剂连接到可检测标签的碱基,其特征在于可断链连接剂包含从以下组中选择的基团:公式(I)(其中X选择从包括O、S、NH和NQ的组中,其中Q是C1-10取代或未取代的烷基,Y选择从包括O、S、NH和N(烯丙基)的组中,T是氢或C1-10取代或未取代的烷基,*表示基团连接到核苷酸或核苷的其余部分处)。
