    摘要: Many areas of biomedical research depend on the analysis of uncommon variations in individual genes or transcripts. Here we describe a method that can quantify such variation at a scale and ease heretofore unattainable. Each DNA molecule in a collection of such molecules is converted into a single particle to which thousands of copies of DNA identical in sequence to the original are bound. This population of beads then corresponds to a one-to-one representation of the starting DNA molecules. Variation within the original population of DNA molecules can then be simply assessed by counting fluorescently-labeled particles via flow cytometry. Millions of individual DNA molecules can be assessed in this fashion with standard laboratory equipment. Moreover, specific variants can be isolated by flow sorting and employed for further experimentation. This approach can be used for the identification and quantification of rare mutations as well as to study variations in gene sequences or transcripts in specific populations or tissues.

    摘要: In some embodiments, methods for obtaining sequence information from a nucleic acid template linked to a support include hybridizing a first primer to a template strand linked to a support, sequencing a portion of the nucleic acid template, thereby forming an extended first primer product that is complementary to a portion of the nucleic acid template. In some embodiments, the method further includes introducing a nick into a portion of the template strand that is hybridized to the extended first primer product, degrading a portion of the template strand from the nick using a degrading agent, where a portion of the extended first primer remains hybridized to an undegraded portion of the template strand, and sequencing at least some of the single-stranded portion of the extended first primer by synthesis.
