Abstract:
Methods, software, and systems for aligning a read sequence to a reference sequence are disclosed. In certain embodiments, the methods, software, and systems involve determining similarity of distribution of k-mers between a region of the read sequence and a region of the reference sequence in order to determine whether the region of the read sequence maps to the region of the reference sequence.
Abstract:
The invention is a novel Y-shaped (forked) adaptor containing primer-binding sites and barcodes in each of the single-stranded portions for sequencing nucleic acids with a reduced rate of errors.
Abstract:
The invention is directed to a preserved serial set of sequential, iterative, and ordered thin sections of a specimen block, and a catalogue of images taken from one or more sub-series of the set of sections and organized so as to create a three-dimensional profile of the microscopic structures of the specimen block. The serial set of sequential, iterative, and ordered thin sections are prepared from the specimen block by cutting and imaging thin sections of that specimen block so that the thin sections remain strictly in the sequential, iterative, order in which they are cut from the specimen block. A spatial index is created from the catalogued three-dimensional images which is searchable by local content-based image retrieval (LCBIR). The LCBIR query is used to locate, within the three-dimensional index, microscopic structural features, thereby making that portion of the specimen available for further analysis and/or for extraction.
Abstract:
In accordance with embodiments herein a method for capturing cells of interest in a digital microfluidic system is provided, comprising utilizing a droplet actuator to transport a sample droplet to a microwell device. The microwell device includes a substrate having a plurality of microwells that open onto a droplet operations surface of the microwell device. The sample droplet includes cells of interest that enter the microwells. The method introduces capture beads to the microwells, and the capture elements are immobilized on the capture beads. The method utilizes the droplet actuator to transport a cell lysis reagent droplet to the microwell device. Portions of the cell lysis reagent droplet enter the microwells and, during an incubation period, cause the cells of interest to release analyte that is captured by the capture elements on the capture beads.
Abstract:
A composition and method for controlled in vitro fragmentation of nucleic acids. A transposase forms catalytically active complexes with a modified transposon end that contains within its end sequence degenerate, apurinic/apyrimidinic sites, nicks, or nucleotide gaps, to fragment or shear a target nucleic acid sample in a controlled process. This method yields desired average nucleic acid fragment sizes. The inventive composition and method may be applied for generation of DNA fragments containing shortened transposon end sequences to facilitate subsequent reactions, for production of asymmetrically tailed DNA fragments, etc.
Abstract:
Subject of the invention is a calibration probe for calibrating an electronic device, such as a DNA sequencer, for analysing biomolecules by detecting fluorescent signals from a sample probe, wherein the calibration probe comprises a detection area for detection of fluorescent signals with the electronic device during calibration, wherein the detection area comprises at least one fluorescent dye attached thereto, wherein the at least one fluorescent dye is attached to first defined regions of the detection area, whilst not being attached to second defined regions of the detection area. The invention also relates to uses of the calibration probe, methods for calibrating the electronic device and methods for analysing biomolecules by detecting fluorescent signals.
Abstract:
The disclosure provides methods to assemble genomes of eukaryotic or prokaryotic organisms. The disclosure provides methods for haplotype phasing and meta-genomics assemblies. The disclosure provides a streamlined method for accomplishing these tasks, such that intermediates need not be labeled by an affinity label to facilitate binding to a solid surface. The disclosure also provides methods and compositions for the de novo generation of scaffold information, linkage information, and genome information for unknown organisms in heterogeneous metagenomic samples or samples obtained from multiple individuals. Practice of the methods can allow de novo sequencing of entire genomes of uncultured or unidentified organisms in heterogeneous samples, or the determination of linkage information for nucleic acid molecules in samples comprising nucleic acids obtained from multiple individuals.
Abstract:
The present invention relates to DNA microscopy methods to record the cellular co- localization and/or spatial distributions of arbitrary nucleic acid sequences, or other biomolecules tagged with nucleic sequences. The method involves sequence-components which may identify the targeted sequences-of-interest themselves and/or spatial beacons relative to which their distances are measured.
