Abstract

The Golgi auto-antigens recognized by five human autoimmune sera were characterized with anti-Golgi auto-antibodies. The five sera showed strong anti-Golgi reactivity, together with weak anti-nuclear reactivity, as assessed by indirect immunofluorescence using the human HEp2 epithelial cell line. The Golgi auto-antigens recognized by the autoimmune sera were identified by immunoprecipitation and immunoblotting of post-nuclear supernatants. These sera reacted with at least 14 components of molecular mass (M(r)) 35-260 kDa; three components were detected only by immunoprecipitation, six components detected only by immunoblotting and five components appear to be detected by both techniques. We ..
