  • Publication number: 20110177587
    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.

  • Patent number: 7244567
    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.
