  • Publication number: 20170029857
    Abstract: Methods for amplifying nucleic acids are provided. The methods can be used to minimise sequence specific bias caused by the preferential amplification of certain nucleic acid sequences. Methods are described which can lower the efficiency of AT rich templates relative to GC rich templates, thereby minimising GC bias during amplification reactions with multiple templates of different sequence. The methods are suited to solid phase amplification, for example, utilising flow cells.

  • Publication number: 20160115461
    Abstract: Modified DNA polymerases have an affinity for DNA such that the polymerase has an ability to incorporate one or more nucleotides into a plurality of separate DNA templates in each reaction cycle. The polymerases are capable of forming an increased number of productive polymerase-DNA complexes in each reaction cycle. The modified polymerases may be used in a number of DNA sequencing applications, especially in the context of clustered arrays.

  • Publication number: 20160090623
    Abstract: The invention relates to methods for pairwise sequencing of a double-stranded polynucleotide template, which methods result in the sequential determination of nucleotide sequences in two distinct and separate regions of the polynucleotide template. Using the methods of the invention it is possible to obtain two linked or paired reads of sequence information from each double-stranded template on a clustered array, rather than just a single sequencing read from one strand of the template.

  • Publication number: 20150337297
    Abstract: The present invention provides methods for creating an array of features on a surface based on content transferred from a plurality of beads to the surface. Nucleic acid content can be transferred using a method including the steps of (a) providing a surface having one or more primer oligonucleotides attached to the surface; (b) providing a pool of beads, wherein beads in the pool have a plurality of templates attached thereto, the plurality comprising multiple copies of a single nucleic acid template sequence; (c) arraying the beads onto the surface by hybridizing the templates to the primer oligonucleotides; and (d) extending the primers to produce copies of the templates attached to the surface.

  • Publication number: 20150225787
    Abstract: Provided herein is a method for sequencing a polynucleotide molecules. The method includes the steps of providing a plurality of polynucleotide molecules attached to a surface, wherein a first portion of each polynucleotide molecule is attached to a first location of the surface and a second portion of each polynucleotide molecule is attached to a second location of the surface, the relative proximity of the first and second locations being correlated with the probability that the first and second portions are paired, separating the first and second portions of the polynucleotide molecules on the surface, determining the sequences of the first and second portions of the polynucleotide molecules and comparing the relative proximities and the sequences to determine which first and second portions are paired and to determine the sequence of the target polynucleotide molecules.
