Abstract: An example method includes reacting a first solution and a different, second solution on a flow cell by flowing the first solution over amplification sites on the flow cell and subsequently flowing the second solution over the amplification sites. The first solution includes target nucleic acids and a first reagent mixture that comprises nucleoside triphosphates and replication enzymes. The target nucleic acids in the first solution transport to and bind to the amplification sites at a transport rate. The first reagent mixture amplifies the target nucleic acids that are bound to the amplification sites to produce clonal populations of amplicons originating from corresponding target nucleic acids. The amplicons are produced at an amplification rate that exceeds the transport rate. The second solution includes a second reagent mixture and lacks the target nucleic acids. The second solution is to increase a number of the amplicons at the amplification sites.

Abstract: The disclosed embodiments concern methods, apparatus, systems and computer program products for determining the presence or absence of repeat expansions of interest, including repeat expansions of repeat sequences that are medically significant. Some embodiments provide methods for identifying and calling medically relevant repeat expansions using anchored reads. An anchored read is a paired end read that is unaligned to a repeat sequence under consideration, but it is paired with an anchor read that is aligned to or near the repeat sequence. Some embodiments use both anchor and anchored reads to determine the presence or absence of the repeat expansions. System, apparatus, and computer program products are also provided for determining repeat expansion implementing the methods disclosed.

Abstract: Polynucleotide sequencing methods employ a sequencing oligonucleotide that hybridizes to a free 3? end potion of a template polynucleotide strand with greater affinity than a surface oligonucleotide. Such sequencing oligonucleotides may be used as a primer to determine the sequence of an index sequence by extending the sequencing oligonucleotide using the template strand as a template. Sequencing processes that employ such sequencing oligonucleotides provide a sufficiently intense signal to determine to the sequence of the index sequence.
