摘要:
Random arrays of single molecules are provided for carrying out large scale analyses, particularly of biomolecules, such as genomic DNA, cDNAs, proteins, and the like. In one aspect, arrays of the invention comprise concatemers of DNA fragments that are randomly disposed on a regular array of discrete spaced apart regions, such that substantially all such regions contain no more than a single concatemer. Preferably, such regions have areas substantially less than 1 μm2 and have nearest neighbor distances that permit optical resolution of on the order of 109 single molecules per cm2. Many analytical chemistries can be applied to random arrays of the invention, including sequencing by hybridization chemistries, sequencing by synthesis chemistries, SNP detection chemistries, and the like, to greatly expand the scale and potential applications of such techniques.
摘要:
Disclosed are novel methods and compositions for rapid and highly efficient nucleic acid sequencing based upon hybridization with two sets of small oligonucleotide probes of known sequences. Extremely large nucleic acid molecules, including chromosomes and non-amplified RNA, may be sequenced without prior cloning or subcloning steps. The methods of the invention also solve various current problems associated with sequencing technology such as, for example, high noise to signal ratios and difficult discrimination, attaching many nucleic acid fragments to a surface, preparing many, longer or more complex probes and labelling more species.
摘要:
The invention relates to methods and devices for analyzing single molecules, i.e. nucleic acids. Such single molecules may be derived from natural samples, such as cells, tissues, soil, air and water without separating or enriching individual components. In certain aspects of the invention, the methods and devices are useful in performing nucleic acid sequence analysis by probe hybridization.
摘要:
We provide a DNA sequencing method and a sequencing system where large numbers of sequence reads can be obtained in parallel by running traditional electrophoresis in a special format. Parallelization is obtained either through a 3-dimensional gel-cube or through bundled capillary tubes including fiber-optic tubes or other types of micro channels in a bundle or matrix format. Various ways of capturing sequence traces are provided. We also provide two distinct methods for preparing genomic DNA/cDNA fragments: one through universal primer site anchoring and amplification of single molecules, and the other through micro-array/bead oligomer extension and dye-terminator incorporation using target sequence specific primers. The invention can perform large-scale genomic sequencing including sequencing a complete human genome in one or a few runs.

摘要:
Sequencing by Hybridization (SBH) methods and apparatus employing subdivided filters for discrete multiple probe analysis of multiple samples may be used for DNA identification and for DNA sequencing. Partitioned filters are prepared. Samples are affixed to sections of partitioned filters and each sector is probed with a single probe or a multiplexed probe for hybridization scoring. Hybridization data is analyzed for probe complementarity, partial sequencing by SBH or complete sequencing by SBH.
