Fig. 1From: Sulphite oxidase (SO) – a mitochondrial autoantigen as target for humoral and cellular immune reactions in primary sclerosing cholangitisDemonstration of recombinant SO proteins by SDS-PAGE (10%; Coomassie-blue staining). M = molecular weight marker; 1 = SO-fl at 60 kDa; 2 = SO-I at 17 kDa; 3 = SO-II at 32 kDa; 4 = SO-III at 23 kDa. * = bands were excised and confirmed to correspond to SO by MALDI-TOF mass spectrometryBack to article page
