  • Patent number: 8563274
    Abstract: Aspects of the present invention are drawn to processes for moving a region of interest in a polynucleotide from a first position to a second position with regard to a domain within the polynucleotide, also referred to as a “reflex method”. In certain embodiments, the reflex method results in moving a region of interest into functional proximity to specific domain elements present in the polynucleotide (e.g., primer sites and/or MID). Compositions, kits and systems that find use in carrying out the reflex processes described herein are also provided.

  • Publication number: 20130237458
    Abstract: Aspects of the present invention include methods and compositions for determining the number of individual polynucleotide molecules originating from the same genomic region of the same original sample that have been sequenced in a particular sequence analysis configuration or process. In these aspects of the invention, a degenerate base region (DBR) is attached to the starting polynucleotide molecules that are subsequently sequenced (e.g., after certain process steps are performed, e.g., amplification and/or enrichment). The number of different DBR sequences present in a sequencing run can be used to determine/estimate the number of different starting polynucleotides that have been sequenced. DBRs can be used to enhance numerous different nucleic acid sequence analysis applications, including allowing higher confidence allele call determinations in genotyping applications.

  • Patent number: 8476018
    Abstract: The invention provides methods and compositions for attaching oligonucleotide tags to polynucleotides for the purpose of carrying out analytical assays in parallel and for decoding the oligonucleotide tags of polynucleotides selected in such assays. Words, or subunits, of oligonucleotide tags index submixtures in successively more complex sets of submixtures (referred to herein as “tiers” of submixtures) that a polynucleotide goes through while successive words are added to a growing tag. By identifying each word of an oligonucleotide tag, a series of submixtures is identified including the first submixture that contains only a single polynucleotide, thereby providing the identity of the selected polynucleotide. The analysis of the words of an oligonucleotide tag can be carried out in parallel, e.g.

  • Patent number: 8445205
    Abstract: The present invention provides methods and compositions for tagging nucleic acid sequence fragments, e.g., a set of nucleic acid sequence fragments from a single genome, with one or more unique members of a collection of oligonucleotide tags, or sequence tokens, which, in turn, can be identified using a variety of readout platforms. As a general rule, a given sequence token is used once and only once in any tag sequence. In addition, the present invention also provides methods for using the sequence tokens to efficiently determine variations in nucleotide sequences in the associated nucleic acid sequence fragments.

  • Publication number: 20130053253
    Abstract: Aspects of the present invention are drawn to methods and compositions for the genetic analysis of regions of interest from one or more starting polynucleotide sample, e.g., a multiplexed polynucleotide sample. In certain aspects, a polynucleotide sample comprising one or more region of interest (ROI) is subjected to independent amplification reactions for specific sub-regions within the ROI(s). The amount/concentration of the product from each sub-region amplification reaction is determined followed by producing a normalized sample based on the determined amount/concentration that is suitable for further analyses (e.g., sequencing).

  • Patent number: 8241850
    Abstract: The invention is drawn to isolating sequence variants of a genetic locus of interest using a modified iterative primer extension method. The nucleic acids analyzed are generally single stranded and have a reference sequence which is used as a basis for performing iterative single nucleotide extension reactions from a hybridized polymerization primer. The iterative polymerization reactions are configured such that polymerization of the strand will continue if the sequence of the nucleic acid being analyzed matches the reference sequence, whereas polymerization will be terminated if the nucleic acid being analyzed does not match the reference sequence. Nucleic acid strands that have mutations can be isolated using a variety of methods and sequenced to determine the precise identity of the mutation/polymorphism. By performing the method on both strands of the nucleic acid being analyzed, virtually all possible mutations can be identified.

  • Patent number: 8124336
    Abstract: Aspects of the present invention are drawn to methods and compositions for sorting nucleic acid molecules into physically separate compartments according to the identity of a nucleotide base or sequence of bases at a specific location, resulting in the production of reduced complexity samples that find use in any number of downstream genetic analyses. Aspects of the methods of the invention include fragmenting a nucleic acid sample, e.g., with a restriction enzyme, ligating an adaptor (or adaptors), and sorting the fragments based on the identity of the nucleotide base(s) positioned adjacent to the fragmentation site (e.g., the restriction enzyme cut site/or recognition site). Each round of sorting produces binned samples having reduced complexity over the parent sample.
