  • Publication number: 20150344516
    Abstract: 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 C1-10 substituted or unsubstituted alkyl group, Y is selected from the group comprising O, S, NH and N(allyl), T is hydrogen or a C1-10 substituted or unsubstituted alkyl group and * indicates where the moiety is connected to the remainder of the nucleotide or nucleoside).

  • Publication number: 20150343410
    Abstract: The invention relates to methods of generating templates for a nucleic acid sequencing reaction which comprise: providing at least one double-stranded nucleic acid molecule, wherein both strands of the double-stranded nucleic acid molecule are attached to a solid support at the 5? end, cleaving one or both strands of the double-stranded nucleic acid molecule, and subjecting the cleaved strand(s) to denaturing conditions to remove the portion of the cleaved strand(s) not attached to the solid support, thereby generating a partially or substantially single-stranded template for a nucleic acid sequencing reaction.
