    摘要: Devices, assemblies, systems and methods described herein enable detection of as few as a single copy of a target nucleic acid molecule. Polynucleotides copied from a single or a small number of target nucleotide(s) within regions near to an initial copying site may be detected by optical or other methods as disclosed herein. Devices, assemblies and systems may comprise probes and/or primer molecules. Systems comprising optical assemblies, thermal assemblies and reaction assemblies (having reaction chambers for amplification of target nucleic acid molecules) are provided in which used reaction assemblies may be replaced to provide reusable devices. Systems comprising analytical assemblies and detection assemblies are provided in which an assay cartridge having assay chambers may engage a thermal assembly for amplification of target nucleic acid molecules. These devices, systems and methods offer the advantages of detection of as few as a single copy of a target nucleic acid molecule.

    摘要: The present teachings comprise a device and method for lysing and/or purifying biological sample. The device can comprise a cartridge having a chamber containing a biological sample receiving region, a plurality of electrodes, and one or more sieving matrices. The electrodes can be configured to lyse the biological sample through the production of a pulsed electrical field. The electrodes can also be configured to heat lyse the biological sample. The electrodes can also be configured to electrophoretically move the biological sample through one or more sieving matrices. A portion of the sample can be isolated on a membrane. The portion of the sample isolated on the membrane can be amplified and detected. A portion of the sample can be isolated in a collection area present in the cartridge. The portion of the sample isolated in the collection area can be removed from the cartridge.

    摘要: An apparatus for identifying a target portion of a sample. In some embodiments, the sample can be substantially purified and/or amplified in a test chamber. In some embodiments, the sample can be provided in an amount so that amplification is not necessary. The apparatus generally comprises a test chamber having an input region for receiving a sample and an analysis region. A sample chamber can be defined by at least a portion of the test chamber. A separation mechanism can separate a target portion of the sample from the sample and an analysis chamber can aid in analyzing at least the target portion of the sample.
