  • Publication number: 20210047678
    Abstract: Methods and systems are provided for point-of-care nucleic acid amplification and detection. One embodiment of the point-of-care molecular diagnostic system includes a cartridge and an instrument. The cartridge can accept a biological sample, such as a urine or blood sample. The cartridge, which can comprise one or more of a loading module, lysis module, purification module and amplification module, is inserted into the instrument which acts upon the cartridge to facilitate various sample processing steps that occur in order to perform a molecular diagnostic test.
    Type: Application

    Inventors: Sayeed ANDESHMAND, Thomas H. CAULEY, III, John DIXON, David GLADE, Hédia MAAMAR, Michael John McADAMS, Dzam-Si Jesse NG, David Alexander ROLFE
  • Publication number: 20210024980
    Abstract: Disclosed herein are primers and probes related to the detection of Neisseria gonorrhoeae via nucleic acid amplification testing (NAAT), for example to amplify and determine the presence of N. gonorrhoeae nucleic acids present in test samples. Specifically the present disclosure describes primers and probes that bind to Cytochrome C or ccpA gene of N. gonorrhoeae for detection via loop mediated isothermal amplification (LAMP) and molecular beacon hybridization.

  • Publication number: 20190284618
    Abstract: Disclosed herein are primers and probes related to the detection of Neisseria gonorrhoeae via nucleic acid amplification testing (NAAT), for example to amplify and determine the presence of N. gonorrhoeae nucleic acids present in test samples. Specifically the present disclosure describes primers and probes that bind to the small subunit rRNA (cytosine (967)-C(5))-methyltransferase or rsmB gene of N. gonorrhoeae for detection via loop mediated isothermal amplification (LAMP) and molecular beacon hybridization.
