  • Patent number: 7658778
    Abstract: A method for making high temperature filter media includes the steps of melt-spinning a plurality of fibers of pre-ceramic thermoplastic polymer to form a non-woven textile web of the fibers, curing and cross-linking the thermoplastic polymer to a thermo-set polymer and thermally decomposing the thermo-set polymer to ceramic.
    Type: Grant
    Filed: December 16, 2003
    Date of Patent: February 9, 2010
    Assignee: Global Strategic Materials, LLC

  • Patent number: 6492120
    Abstract: This invention relates generally to nucleic acid-based diagnostic assays for detecting, identifying and/or quantitating target sequences in a sample. More specifically, the invention utilizes sequential cleavage of nucleic acids to achieve target and signal amplification through cycling reactions.

  • Patent number: 6114117
    Abstract: The present invention relates to a method, kit and reagent composition for determining the presence of a target nucleic acid in a sample using a two-stage target cycling reaction. During stage 1 of the reaction, the target nucleic acid hybridizes with a probe nucleic acid to effectuate release of an activator into the assay medium. During stage 2 of the reaction, a target analog-anchor complex is cleaved by the activator, which accomplishes the dual purpose of releasing the target analog into the assay medium, and the initiation of signal generation. The released target analog then restarts the cyclic reaction by binding to a second probe, which effectuates release of a second activator, and so on. This cyclic reaction gives rise to an increase in the amount of signal generated from a single target nucleic acid molecule in the sample, which greatly enhances the level of target detection that can be expected.
