Immunoprecipitation and antigen identification with patient serum. A SDS-PAGE of the immunoprecipitates of patient serum 1 (PS1) or control serum (CS) with cerebellar lysates stained with colloidal Coomassie revealed four specific bands (1–4) between 40 and 50 kDa in the eluate fraction of PS1 but not CS. Mass spectrometry analysis identified the following proteins: band 1 septin-6,-7,-11; band 2 septin-6,-7,-11; band 3 septin-3,-5; band 4 septin-3,-5 in the eluate fraction of PS1
