  • Publication number: 20240299945
    Abstract: Embodiments relate to devices, systems, methods and compositions useful for routing and tracking multiple mobile units within a microfluidic device having an inlet channel connected to a multi-way sorting junction, which is fluidly connected with a plurality of 4 or more channels, and a steering mechanism for directing the flow of the mobile units according to a predetermined algorithm. Mobile units can be routed and followed through the microfluidic device in an ordered flow, such that the mobile units are exposed to chemical environments and/or enzymatic synthesis reactions associated with the channels. Mobile units can be steered in multiple directions, between the sorting junctions and the channels by the steering mechanism by changes in flow or pressure. Some such devices, systems, methods and compositions include mobile units that can flow in both the forward and reverse directions and into each of as plurality of 4 or more channels from two sorting junctions.

  • Patent number: 10526601
    Abstract: In certain embodiments, the present invention provides a way of “digitally” marking different the alleles of different chromosomes by using a transposase to insert differently barcoded transposons into genomic DNA before further analysis. According to this method, each allele becomes marked with a unique pattern of transposon barcodes. Because each unique pattern of transposon barcodes identifies a particular allele, the method facilitates determinations of ploidy and copy number variation, improves the ability to discriminate among homozygotes, heterozygotes, and patterns arising from sequencing errors, and allows loci separated by uninformative stretches of DNA to be identified as linked loci, thereby facilitating haplotype determinations. Also provided is a novel artificial transposon end that includes a barcode sequence in two or more positions that are not essential for transposition.

  • Patent number: 9644235
    Abstract: The invention provides an assay method for detection and/or quantification of a plurality of nucleic acid or protein targets in a sample. In the method probes are used to associate a detectable tag sequence with each of the selected targets present in the sample. Probes or primers sufficient to identify at least 25, and preferably at least 500, different targets are used. The method involves segregating aliquots of the sample from each other and detecting the tag sequences in each aliquot.

  • Patent number: 9643178
    Abstract: A variety of elastomeric-based microfluidic devices and methods for using and manufacturing such devices are provided. Certain of the devices have arrays of reaction sites to facilitate high throughput analyzes. Some devices also include reaction sites located at the end of blind channels at which reagents have been previously deposited during manufacture. The reagents become suspended once sample is introduced into the reaction site. The devices can be utilized with a variety of heating devices and thus can be used in a variety of analyzes requiring temperature control, including thermocycling applications such as nucleic acid amplification reactions, genotyping and gene expression analyzes.

  • Patent number: 9623413
    Abstract: Methods and systems are provided for conducting a reaction at a selected temperature or range of temperatures over time. An array device is provided. The array device contains separate reaction chambers and is formed as an elastomeric block from multiple layers. At least one layer has at least one recess that recess has at least one deflectable membrane integral to the layer with the recess. The array device has a thermal transfer device proximal to at least one of the reaction chambers. The thermal transfer device is formed to contact a thermal control source. Reagents for carrying out a desired reaction are introduced into the array device. The array device is contacted with a thermal control device such that the thermal control device is in thermal communication with the thermal control source so that a temperature of the reaction in at least one of the reaction chamber is changed as a result of a change in temperature of the thermal control source.

  • Publication number: 20160153026
    Abstract: High throughput methods are used that combine the features of using a matrix-type microfluidic device, labeled nucleic acid probes, and homogenous assays to detect and/or quantify nucleic acid analytes. The high throughput methods are capable of detecting nucleic acid analyses with high PCR and probe specificity, producing a low fluorescence background and therefore, a high signal to noise ratio. Additionally, the high throughput methods are capable of detecting low copy number nucleic acid analyte per cell.

  • Patent number: 9316331
    Abstract: Multilevel microfluidic devices include a control line that can simultaneously actuate valves for both sample and reagent lines. Microfluidic devices are configured to contain a first reagent in a first chamber and a second reagent in a second chamber, where either or both of the first and second reagents are contained at a desired or selected pressure. Operation of a microfluidic device includes transmitting second reagent from the second chamber to the first chamber, for mixing or contact with the first reagent. Microfluidic device features such as channels, valves, chambers, can be at least partially contained, embedded, or formed by or within one or more layers or levels of an elastomeric block.

  • Publication number: 20160091479
    Abstract: The presence of a detectable entity within a detection volume of a microfabricated elastomeric structure is sensed through a change in the electrical or magnetic environment of the detection volume. In embodiments utilizing electronic detection, an electric field is applied to the detection volume and a change in impedance, current, or combined impedance and current due to the presence of the detectable entity is measured. In embodiments utilizing magnetic detection, the magnetic properties of a magnetized detected entity alter the magnetic field of the detection volume. This changed magnetic field induces a current which can reveal the detectable entity. The change in resistance of a magnetoresistive element may also reveal the passage of a magnetized detectable entity.
