  • Publication number: 20110201508
    Abstract: The invention provides particle compositions having applications in nucleic acid analysis. Nucleic acid polymer particles of the invention allow polynucleotides to be attached throughout their volumes for higher loading capacities than those achievable solely with surface attachment. In one aspect, nucleic acid polymer particles of the invention comprise polyacrylamide particles with uniform size distributions having low coefficients of variations, which result in reduced particle-to-particle variation in analytical assays. Such particle compositions are used in various amplification reactions to make amplicon libraries from nucleic acid fragment libraries.

  • Publication number: 20060228721
    Abstract: The claimed invention provides for new sample preparation methods enabling direct sequencing of PCR products using pyrophosphate sequencing techniques. The PCR products may be specific regions of a genome. The techniques provided in this disclosure allows for SNP (single nucleotide polymorphism) detection, classification, and assessment of individual allelic polymorphisms in one individual or a population of individuals. The results may be used for diagnostic and treatment of patients as well as assessment of viral and bacterial population identification.

  • Publication number: 20060134633
    Abstract: This invention relates to methods of sequencing DNA. More specifically, this invention relates to methods of sequencing both the sense and antisense strands of DNA through the use of blocked and unblocked sequencing primers. In brief, these methods include the steps of annealing an unblocked primer to a first strand of nucleic acid; annealing a second blocked primer to a second strand of nucleic acid; elongating the nucleic acid along the first strand with a polymerase; terminating the first sequencing primer; deblocking the second primer; and elongating the nucleic acid along the second strand.

  • Publication number: 20050227264
    Abstract: Embodiments of the present invention are directed to methods and devices/systems for amplifying genetic material and may include providing a water-in-oil emulsion in a continuous flow. The emulsion may include a plurality of water droplets comprising microreactors. Each of the plurality of microreactors may include a single bead capable of capturing a nucleic acid template, a single species nucleic acid template and sufficient reagents to amplify the copy number of the nucleic acid template. The method also includes flowing the emulsion across a first temperature zone and a second lower temperature zone to thermally process the microreactors to amplify the nucleic acid template by polymerase chain reaction.
