  • Publication number: 20230110385
    Abstract: A system and method for the detection of autoantibodies in saliva is described. In particular, the system is suitable for detecting an autoantibody in a subject, wherein the presence of the autoantibody is indicative of the presence or increased risk of development of an autoimmune disease or disorder.

  • Publication number: 20190078159
    Abstract: The molecules harbored in exosomes play important roles in biological science. A highly desirable goal for exosome research is the rapid, simple, simultaneous tracking and quantification of exosome harbored molecules. Disclosed herein are methods and devices for inducing the release and measurement of biomolecules harbored in exosomes. The disclosed method, Electric Field Induced Release and Measurement (EFIRM) technique, uses an electrical field to simultaneously disrupt exosomes to release the contents and measure the harbored exosomal RNA/proteins. The exosome vesicle contents can be released within minutes. This provides a potential on-site method for the detection of exosome-harbored biomolecules.

  • Publication number: 20190010538
    Abstract: Provided herein is an all-in-one saliva collection apparatus that collects saliva to allow for the filtration of saliva in order to separate saliva components, such as extracellular proteins and nucleic acids that are not present in intact cells, from the intact cells and debris remaining in the extracted sample. The filtered saliva samples can be aliquoted into two fractions for protein and/or nucleic acid analysis. The present invention further describes long term storage at ambient temperatures of filtered salivary nucleic acids, and long term storage at ambient temperatures of filtered salivary proteins added to an ethanol solution. The filtered cell-free saliva samples have diagnostic usefulness.
