  • PLASMA PROCESSING APPARATUS AND PLASMA PROCESSING METHOD
    Publication number: 20240030008
    Abstract: A plasma processing apparatus disclosed herein includes a stage disposed in a processing container and configured to mount thereon a substrate, a rotary driving mechanism configured to rotatably drive the stage, and a plurality of plasma sources provided on an upper wall of the processing container facing the stage. The plurality of plasma sources are not arranged axially symmetrically with respect to a rotation axis of the stage.

  • Anti-human stromelysin monoclonal antibody and method for diagnosis of rheumatoid arthritis by enzyme immunoassay
    Patent number: 5834212
    Abstract: Anti-human stromelysin monoclonal antibodies reactive with latent and active forms of stromelysin without discrimination between the two, each being immunoreactive with only one of the antigenic determinants of human stromelysin, are provided. The use of a combination of two such monoclonal antibodies which specifically react with different antigenic determinants of human stromelysin renders it possible to accurately determine the amount of human stromelysin in human body fluids, and thus to carry out the diagnosis of rheumatoid arthritis.There are thus provided said monoclonal antibodies per se, a sandwich enzyme immunoassay for the determination of the amount of human stromelysin in human body fluid samples using a combination of two such monoclonal antibodies, and a method for the diagnosis of rheumatoid arthritis using said immunoassay.

  • Method for the diagnosis of rheumatoid arthritis
    Patent number: 5190861
    Abstract: A method for diagnosing rheumatoid arthritis, which is characterized by enzyme-immunologically measuring the amount of collagenase inhibitor present in sera, plasmas or synovial fluids by way of a sandwich assay wherein two different monoclonal antibodies which specifically bind to different antigenic determinants of the collagenase inhibitor are used, and comparing the measured amount with that for normal subjects.
