[Recent advances and the clinical usefulness of detection techniques for antinuclear antibodies]

Fluorescent antinuclear antibodies (FANA) have been routinely tested at general clinical settings. Newly developed immunochemical assays using recombinant nuclear antigens have recently been introduced, but their clinical significance and usefulness have not yet been established. In this symposium six papers dealing with FANA, cloning of nuclear antigen genes, enzyme immunoassay systems for ANA, idiotype of ANA, anti Na, anti PCNA etc. are presented and discussed.
