  • Patent number: 11761025
    Abstract: A method for preserving and processing cell-free nucleic acids located within a blood sample is disclosed, wherein a blood sample containing cell-free nucleic acids is treated to reduce both blood cell lysis and nuclease activity within the blood sample. The treatment of the sample aids in increasing the amount of cell-free nucleic acids that can be identified and tested while maintaining the structure and integrity of the nucleic acids.

  • Patent number: 11708614
    Abstract: Assays and methods for detecting resistance to beta-lactam antibiotics including detection of multiple ?-lactamase family specific gene targets by polymerase chain reaction or microarray. One or more kits including primers and/or probes for identification of ?-lactamase genes selected from the group consisting of one or more of the following: MOX-like, FOX-like, ACC-like, ACT/MIR-like, CMY-2-like, DHA-like, CTX-M-14-like, CTX-M-15-like, VIM-like, NDM-like, IMP-like, KPC-like, and OXA-48-like, OXA-51-like, OXA-143-like, OXA-58-like, OXA-23-like, OXA-24/40-like, TEM-like, and SHV-like. A kit may also include one or more primers and/or probes for the identification a non-beta lactamase gene family which confers antibiotic resistance, such as the MCR-1 gene.

  • Patent number: 11647743
    Abstract: The claimed subject matter comprises a device to collect and preserve cells comprising of: (1) a collection container comprised of a tube having an open end and a closed end, a closure in the open end of the tube, a vacuum drawn to a predetermined level inside the container; and (2) compounds including an anticoagulant agent and a fixative agent, wherein the compounds are in a sufficient amount to preserve said cells” original morphology and antigenic sites without significant dilution of said cells, and thereby allowing said cells to be directly analyzed by a flow cytometer without further treatment.

  • Patent number: 11634747
    Abstract: A method for preserving and processing fetal nucleic acids located within maternal plasma is disclosed, wherein a sample of maternal blood containing fetal nucleic acids is treated to reduce both cell lysis of the maternal blood cells and deoxyribonuclease (DNase) and ribonuclease (RNase) activity within the fetal nucleic acids. The treatment of the sample aids in increasing the amount of fetal nucleic acids that can be identified and tested while maintaining the structure and integrity of the fetal nucleic acids.
