  • Patent number: 11293067
    Abstract: The present application provides a method for genotyping M. tuberculosis, comprising obtaining amplifying and obtaining a first DNA fragment from a DNA sample by using one or more primer sets selected from the group consisting of primer sets 1 to 25 (SEQ ID Nos. 1 to 50); amplifying and obtaining a second DNA fragment from the obtained first DNA fragment by using one or more extension primers selected from the group consisting of SEQ ID Nos. 51 to 75; and detecting the second DNA fragment by using mass spectrometry, particularly by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS).

  • Patent number: 7807378
    Abstract: The present invention relates to methods of diagnosing myasthenia gravis in a subject, by determining an amount of at least one autoantibody that specifically binds one or more autoantigens selected from heat-shock protein 60 (hsp60), heat-shock protein 90, alpha isoform (hsp90?), and heat-shock protein 90, beta isoform (hsp90?). The invention also provides diagnostic kits for identifying a subject having myasthenia gravis.

  • Publication number: 20100129408
    Abstract: The present invention relates to a Klebsiella pneumoniae gene-deleted mutant and its producing methods. The main objective of this invention is to construct a Klebsiella pneumoniae tonB deletion mutant used as an immunogenically effective amount of a live attenuated vaccine against the community-acquired pyogenic liver abscess, where the tonB gene was deleted. The tonB deletion mutant maintained the structure of the capsular polysaccharide on cell membrane surface, and induced no disease on the mouse after injection. In addition, the tonB deletion mutants induced the immunity against pyogenic liver abscess caused by Klebsiella pneumoniae.

  • Patent number: 7718366
    Abstract: Methods, compounds, and kits for the diagnosis or screening of osteonecrosis are described, and the development of animal models for COL2A1 function in osteonecrosis is put forth. Novel mutations in the COL2A1 gene are identified that are associated with avascular necrosis of the femoral head. Methods of treatment of osteonecrosis and avascular necrosis of the femoral head, including gene therapy approaches comprising introduction of COL2A1 nucleic acid are contemplated.
