  • Patent number: 7488579
    Abstract: This invention presents a set of methods to extract DNA, RNA and protein simultaneously from biomaterials by reagents with high pH. DNA and RNA can be extracted from a upper aqueous phase simultaneously either together as a DNA and RNA mixture or separated DNA and RNA. Protein can be extracted from lower organic phase. The DNA and RNA mixture can be used either as DNA or RNA directly depending on applications without further separation, or as resource for the separated DNA and RNA that can be selected from the DNA and RNA mixture by selective precipitation and/or by selective enzyme digestions. This invention provides the choice of extraction either of DNA and RNA mixture or of separated DNA and RNA simultaneously, as well as extraction of protein from the same piece of biomaterials in high quality, which is very critical for biomaterials with limited resource, such as clinical specimens.

  • Patent number: 6617116
    Abstract: Assay devices, kits, and methods for detection of one or more analytes in a sample are provided. The assay device features the controlled release of reagents and hence is particularly suitable for binding assays such as immunoassays. The assay device achieves greater sensitivity than conventional rapid test assays, leading to stronger and/or more stable visual signals than those produced by conventional devices, easier interpretation of results, and reduced occurrence of indeterminate results. The device can be used for detecting analyte in a variety of biological samples without the need for conventional sample filtration techniques, and thus is suitable for use by untrained personnel without specialized equipment. In addition, the device can be used to simultaneously analyze a number of analytes using a single sample.

  • Patent number: 6393111
    Abstract: A network interface for home networking implemented upon an existing 4-wire (two-pair) phone line system is disclosed. The interface comprises two transmitters, two line isolators and a receiver. The two transmitters transmit data simultaneously to both of the pairs of wires in the phone line system so that all devices coupled to the phone line system, regardless which pair of wires being coupled onto, can receive the data. Because all the pairs carry the data, there is therefore needed one on receiver in the interface to receive the data transmitting over the phone line system. The disclosed interface provides a solution to the home networking which no longer requires the knowledge of the underlying wiring structure in the phone line system.
