SOD1 and amyotrophic lateral sclerosis: The polyclonal antibodies called SEDI and 131–153 Ra-ab were raised against the peptides containing the dimer-interface region (SEDI, Arg 143 - Ile 151; 131–153 Ra-ab, Asn 131 - Gln 153; Fig. 8a and b) [28, 46] and again exclusively immunostained the inclusions in the affected spinal motor neurons of SOD1-ALS patients [16, 28, 47–50].
