  • Publication number: 20190352327
    Abstract: Embodiments of the present disclosure relate to methods of preparation of templates for polynucleotide sequencing. In particular, the disclosure relates to linearization of clustered polynucleotides in preparation for sequencing by cleavage of one or more first strands of double-stranded polynucleotides immobilized on a solid support by a transition metal complex, for example, a palladium complex or a nickel complex. Further disclosure relate to linearization of clustered polynucleotides by cleaving one or more second strands of double double-stranded polynucleotides immobilized on a solid support comprising azobenzene linker by Na2S2O4. Nucleotides and oligonucleotides comprising a 3? phosphate moiety blocking group, and methods of removing the same using a fluoride reagent are also disclosed.

  • Patent number: 10378051
    Abstract: A reaction mixture including (a) a nucleic acid having a primer hybridized to a template, (b) nucleotide analogs, wherein the nucleotide analogs have a blocking moiety; (c) a polymerase that is capable of forming an extended primer by adding the nucleotide analogs to the primer, and (d) a deblocking agent that is capable of removing the blocking moiety from the extended primer. Also provided is a method of synthesizing a polynucleotide including sequentially adding a plurality of the different nucleotides analogs to the nucleic acid via several reaction cycles in the reaction mixture, wherein each reaction cycle includes (i) the polymerase adding a nucleotide analog to the nucleic acid to form a transient nucleic acid species comprising a blocking moiety, and (ii) the deblocking agent modifying the transient nucleic acid species to remove the blocking moiety.
