Immunoprecipitation assay with myositis-specific autoantibodies. Polypeptides immunoprecipitated from 35S-methionine-labelled K562 cell extracts by antibodies from patient sera were separated by SDS–polyacrylamide gelelectrophoresis and visualized by autoradiography. Sera used for immunoprecipitation included serum from a healthy individual (NS), anti-Jo-1, anti-PL-12, anti-PL-7, anti-EJ, anti-KS, anti-OJ, anti-Zo, anti-SRP, anti-Mi-2, anti-SAE, anti-p155/140, anti-p140 (reproduced from [6], by permission of The British Society for Rheumatology)
