  • Patent number: 11822067
    Abstract: The invention relates to an automatic focusing apparatus for the microscopic examination of a plurality of spatially distributed (biological) samples, whereby an object stage that is vertically movable relative to the microscope has a carriage that is translatable along the x-axis and y-axis and a sample stage that is translatable along the z-axis and is mounted on the carriage. Furthermore, the invention relates to a method for automatic focusing and microscopic examination of a plurality of spatially distributed biological samples, through a microscope having an object stage that is vertically movable relative to the microscope.
    Type: Grant

  • Patent number: 11549952
    Abstract: The invention relates to an in vitro method for the diagnosis of acute pancreatitis (AP) in a subject by detection of Glycoprotein 2 isoform alpha (GP2a) protein.
    Type: Grant

  • Patent number: 11340235
    Abstract: The invention relates to a method for binding or capturing autoantibodies directed to various Glycoprotein 2 (GP2) isoforms. In particular the invention provides an in vitro method for the diagnosis of an autoimmune disorder by the detection of autoantibodies that bind one or more isoforms of GP2. The invention is characterized by the provision of multiple isoforms of GP2 as autoantibody targets and encompasses the practical utilization of the finding that the isoform specificity of anti-GP2 autoantibodies enables determination of particular autoimmune diseases. The invention also provides a system and kit developed for carrying out the claimed method. The present invention is useful for determining whether a sample from an individual comprises autoantibodies associated with an autoimmune disease, and for differentiating between multiple autoimmune diseases that exhibit similar symptoms, such as Celiac disease (CeD), Crohn's disease (CD), primary sclerosing cholangitis (PSC), and/or ulcerative colitis (UC).

  • Patent number: 9772331
    Abstract: The invention relates to a method and system for disease diagnosis that simultaneously detects antibodies bound to cellular and/or tissue substrates and antibodies bound to synthetic substrates, such as microparticles or beads coated with specific antigens, thereby providing a “one-step” method for the simultaneous detection and characterization of disease-associated antibodies at both low (cellular and/or tissue) and high (antigen) specificity.
