| Product Name | Jo-1, Thymus (Histidyl t-RNA Synthetase) |

| Description | Purified from calf and/or rabbit thymus through the use of immobilized human anti-Jo-1 immune globulins. Other antigens (Sm, RNP, SSA, Scl-70, and SSB) are not detected with ELISA assays. Homogeneity is verified by SDS PAGE. The Jo-1 antigen is histidyl-transfer ribonucleic acid (t-RNA) synthetase. This enzyme is partially responsible for attaching t-RNA to their cognate rRNA (2). The Jo-1 antigen migrates as a 53 kD protein on SDS-PAGE. Anti-Jo-1 autoantibodies were originally described as precipitating autoantibodies in sera of patients with polymyositis. It was later realized that the anti-Jo-1 antibodies were specific for patients with polymyositis. The target for the anti-Jo-1 antibodies was one of a family of distinct cellular enzymes, the aminoacyl t-RNA synthetases (1). The presence of autoantibodies against the Jo-1 antigen has been reported in up to 23% of polymyositis patients by immunodiffusion (3). Anti-Jo-1 antibodies are almost completely specific for myositis, being mor |
