    摘要: The present invention provides an apparatus and method for disrupting cells or viruses to release the nucleic acid therefrom. The apparatus includes a container having a chamber for holding the cells or viruses. The apparatus also includes an ultrasonic transducer for contacting a wall of the chamber and for transmitting ultrasonic energy into the chamber through the wall. A support structure holds the container and the transducer against each other such that the transducer contacts the wall of the chamber. The support structure includes an elastic body, such as a spring, for applying to the container or to the transducer a substantially constant force to press together the transducer and the wall. The chamber also preferably contains beads for enhancing the disruption of the cells or viruses. The apparatus performs rapid and consistent lysis of cells or viruses, often in as little time as 5 to 10 seconds.

    摘要: An integrated cartridge for sample processing and analysis is disclosed. The integrated cartridge contains a sample preparation chamber having a sample inlet and a sample outlet, and a sample purification chamber adapted to receive a replaceable sample purification unit containing a housing and an extraction filter inside the housing. The extraction filter specifically binds to a molecule of interest. The sample purification chamber has a sample inlet that is in fluid communication with the sample outlet of the sample preparation chamber. Also disclosed is a microarray-based sample analysis (MBSA) system.

    摘要: Methods and devices for isolating nucleic acids from a mixture containing such nucleic acids and extraneous matter are provided. In one embodiment, the method of the invention comprises passing the mixture through a glass frit under conditions effective to separate the nucleic acids from the extraneous matter. In a more specific embodiment, the glass frit is a sintered glass fit.
