  • Publication number: 20130266948
    Abstract: Cartridges for the isolation of a biological sample and downstream biological assays on the sample are provided, as are methods for using such cartridges. In one embodiment, a nucleic acid sample is isolated from a biological sample and the nucleic acid sample is amplified, for example by the polymerase chain reaction. The cartridges provided herein can also be used for the isolation of non-nucleic acid samples, for example proteins, and to perform downstream reactions on the proteins, for example, binding assays. Instruments for carrying out the downstream biological assays and for detecting the results of the assays are also provided.

  • Publication number: 20130236907
    Abstract: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.

  • Publication number: 20120288897
    Abstract: An apparatus includes a housing, a reaction vial and a transfer mechanism. The housing defines a first flow path and a second flow path. The housing has transfer port defining an opening in fluid communication with the second flow path and a volume outside of the housing. The transfer port includes a flow control member to limit flow through the opening. The reaction vial is coupled to the housing and defines a reaction volume, which is in fluid communication with the transfer port via the second flow path. The transfer mechanism is configured to transfer a sample from an isolation chamber of an isolation module to the reaction chamber via at least the first flow path when the transfer mechanism is actuated. The transfer mechanism configured to produce a vacuum in the reaction vial to produce a flow of a sample from the isolation chamber to the reaction volume.

  • Publication number: 20120288866
    Abstract: The embodiments described herein relate to systems and methods for producing an evaporation barrier in a PCR vial. In some embodiments, beads with a particular distribution in diameters can be used to produce a barrier for reducing the evaporation of liquid PCR samples within the PCR vial. In some embodiments, the beads can be pre-filled in the PCR vial. In use, liquid samples and/or liquid reagents can be introduced in the PCR vial pre-filled with the beads, such that the beads can be driven to the surface of the liquid PCR sample through the buoyancy of the beads.

  • Publication number: 20120244534
    Abstract: The invention is directed to systems, methods, and apparatus for carrying out multi-stage amplification reactions, especially under fluidly closed conditions. In one aspect, methods of the invention are carried out in a fluidly closed reaction system that permits the isolation of a portion of a first (or prior) reaction mixture and its use as a sample or specimen in a second (or subsequent) reaction mixture, thereby substantially avoiding interfering effects that first reaction components may have in the second reaction if both reaction mixtures were simply combined together. In this aspect, systems, methods, and apparatus of the invention may be used with any amplification reaction that permits multiple stages of amplification based on the use of nested primers.

  • Patent number: 8268603
    Abstract: An apparatus for disrupting cells or viruses comprises a container having a chamber for holding the cells or viruses. The container includes at least one flexible wall defining the chamber. The apparatus also includes a transducer for impacting an external surface of the flexible wall to generate pressure waves in the chamber. The apparatus also includes a pressure source for increasing the pressure in the chamber. The pressurization of the chamber ensures effective coupling between the transducer and the flexible wall. The apparatus may also include beads in the chamber for rupturing the cells or viruses.

  • Publication number: 20120171758
    Abstract: The present invention provides a cartridge for analyzing a fluid sample. The cartridge provides for the efficient separation of cells or viruses in the sample from the remaining sample fluid, lysis of the cells or viruses to release the analyte (e.g., nucleic acid) therefrom, and optionally chemical reaction and/or detection of the analyte. The cartridge is useful in a variety of diagnostic, life science research, environmental, or forensic applications for determining the presence or absence of one or more analytes in a sample.
