Patent number: 10221452Abstract: 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.Type: GrantFiled: October 12, 2015Date of Patent: March 5, 2019Assignee: ILLUMINA CAMBRIDGE LIMITEDInventors: Roberto Rigatti, Tobias William Barr Ost

Patent number: 10059928Abstract: 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.Type: GrantFiled: June 9, 2017Date of Patent: August 28, 2018Assignee: ILLUMINA CAMBRIDGE LIMITEDInventors: Geoffrey Paul Smith, Roberto Rigatti, Tobias William Barr Ost, Shankar Balasubramanian, Raquel Maria Sanches-Kuiper

Publication number: 20170283870Abstract: This invention relates to improved methods and kits for identification of 5-formylcytosine (5fC) to be distinguished from cytosine (C) in a sample nucleotide sequence. Methods comprise reducing a first portion of polynucleotides which comprise the sample nucleotide sequence; treating the reduced first portion and a second portion of polynucleotides with bisulfite; sequencing the polynucleotides in the first and second portions of the population to produce first and second nucleotide sequences respectively and; identifying the residues in the first and second nucleotide sequences which correspond to a cytosine residue in the sample nucleotide sequence. These methods may be useful, for example in the analysis of genomic DNA and/or of RNA.Type: ApplicationFiled: September 7, 2015Publication date: October 5, 2017Inventors: Tobias William Barr OST, Neil Matthew BELL, Maria Chiara Erminia CATENAZZI
