Fig. 1From: Inflammatory myopathy with anti-signal recognition particle antibodies: case series of 100 patientsRNA immunoprecipitation assay. Urea and 8 % PAGE of phenol-extracted immunoprecipitation from HeLa cell extracts were developed with silver staining. Total RNA indicates 7S RNA and transfer RNA regions. The serum samples #2 and #6 contained anti-signal recognition particle (SRP) antibodies. In contrast, one of autoantibodies against aminoacyl transfer RNA synthetase, anti-PL-7 antibody (anti-threonyl-tRNA synthetase) was found in serum #5Back to article page
