  • INTRODUCTION

    Antinuclear antibodies (ANA) are a group of autoantibodies that specifically target substances in the nucleus of cells. One group of ANAs represent autoantibodies against extractable nuclear antigens, such as SS-A/Ro, SS-B/La, Sm, RNP, Scl-70 and Jo-1, which are mainly ribonucleoproteins and nuclear enzymes. Another group of ANAs are against nucleic acids (dsDNA), complexes of nuclear proteins and histones.

    Detection and classification of these ANAs in human blood are important for differential diagnosis of systemic autoimmune diseases (SAD). Utilization of high-quality autoantigens for the screening and semi-quantification of specific ANAs has been routinely used in clinical practice for precision diagnosis and monitoring the progression of these diseases.
