The paraffin-embedded human brain sections were deparaffinzed likewise. Immunostaining for Annexin A7 was performed using the monoclonal antibody mAb 203–217. Microwave pre-treatment was used for all sections [15]. Trypsin pre-treatment was used as indicated. Carbocyanine 2 and 3 labeled anti-mouse IgG secondary antibodies (Dianova, Hamburg, Germany) were used to detect the primary antibody and showed similar staining patterns. Blank controls were performed, too.
