SRP54 enzyme-linked immunosorbent assay (ELISA). (a) Antibodies reactive with recombinant SRP54 protein by ELISA in sera from patients with anti-7S RNA positive myopathy, myositis without autoantibodies, myasthenia gravis, muscular dystrophy, and healthy controls. The cut-off level for positivity of anti-SRP54 antibody index is indicated by the broken line. (b) Serial changes of anti-SRP54 antibody index between pre- and post-treatment in 10 patients with anti-SRP antibodies. (c) Correlation of anti-SRP54 antibody index determined by ELISA and serum creatine kinase in 100 patients with anti-SRP antibodies
