diagnostic agent and therapeutic for the treatment of autoimmune hepatitis

摘要

SLA/LP-antigens-1 and -2 are new. A diagnostic agent to recognize autoimmune hepatitis is characterized by recognizing a patient antibody against an antigen. The diagnostic agent amino acid sequence corresponds to all (or part) of a 444 or 496 amino acid sequence (given in the specification) and can recognize an SLA/LP-autoantibody. Independent claims are also included for: (1) a cDNA for all or part of a natural or artificial variant antigen as above; (2) a method to detect SLA/LP-antigen as above; and (3) an immunoassay to perform a detection method as in (2).
